74ABT245
Octal transceiver with direction pin; 3-State
Rev. 4 — 6 October 2017 Product data sheet
1 General description
The 74ABT245 high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT245 is an octal transceiver featuring non-inverting 3-state bus compatible
outputs in both send and receive directions. The control function implementation
minimizes external timing requirements. The device features an output enable (OE) input
for easy cascading and a direction (DIR) input for direction control.
2 Features and benefits

3-State buffers
Output capability: +64 mA/–32 mA
Power-up 3-State
Live insertion/extraction permitted
Inputs are disabled during 3-state mode
Latch-up protection exceeds 500 mA per JESD78 class II level A
ESD protection:
HBM JESD22-A114F exceeds 2000 V

and shall have no liability for the consequences of use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the
relevant full data sheet, which is available on request via the local Nexperia
sales office. In case of any inconsistency or conflict with the short data sheet,
the full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be
valid in which the Nexperia product is deemed to offer functions and qualities
beyond those described in the Product data sheet.

Limited warranty and liability — Information in this document is believed
to be accurate and reliable. However, Nexperia does not give any
representations or warranties, expressed or implied, as to the accuracy
or completeness of such information and shall have no liability for the
consequences of use of such information. Nexperia takes no responsibility

or replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory. Notwithstanding any damages that
customer might incur for any reason whatsoever, Nexperia's aggregate and
cumulative liability towards customer for the products described herein shall
be limited in accordance with the Terms and conditions of commercial sale of
Nexperia.
Right to make changes — Nexperia reserves the right to make changes
to information published in this document, including without limitation
specifications and product descriptions, at any time and without notice. This
document supersedes and replaces all information supplied prior to the
publication hereof.
Suitability for use — Nexperia products are not designed, authorized or
warranted to be suitable for use in life support, life-critical or safety-critical
systems or equipment, nor in applications where failure or malfunction
of an Nexperia product can reasonably be expected to result in personal
injury, death or severe property or environmental damage. Nexperia and its
suppliers accept no liability for inclusion and/or use of Nexperia products in
such equipment or applications and therefore such inclusion and/or use is at
the customer’s own risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia makes no representation
or warranty that such applications will be suitable for the specified use
without further testing or modification. Customers are responsible for the
design and operation of their applications and products using Nexperia
products, and Nexperia accepts no liability for any assistance with
applications or customer product design. It is customer’s sole responsibility
to determine whether the Nexperia product is suitable and fit for the
customer’s applications and products planned, as well as for the planned
application and use of customer’s third party customer(s). Customers should
provide appropriate design and operating safeguards to minimize the risks
associated with their applications and products. Nexperia does not accept
any liability related to any default, damage, costs or problem which is based
on any weakness or default in the customer’s applications or products, or
the application or use by customer’s third party customer(s). Customer is
responsible for doing all necessary testing for the customer’s applications
and products using Nexperia products in order to avoid a default of the
applications and the products or of the application or use by customer’s third
party customer(s). Nexperia does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — Nexperia products are
sold subject to the general terms and conditions of commercial sale, as
published at http://www.nexperia.com/profile/terms, unless otherwise agreed
in a valid written individual agreement. In case an individual agreement is
concluded only the terms and conditions of the respective agreement shall
apply. Nexperia hereby expressly objects to applying the customer’s general
terms and conditions with regard to the purchase of Nexperia products by
customer.
No offer to sell or license — Nothing in this document may be interpreted
or construed as an offer to sell products that is open for acceptance or
the grant, conveyance or implication of any license under any copyrights,
