74LVC245A; 74LVCH245A

Octal bus transceiver; 3-state

Rev. 10 — 5 August 2020 Product data sheet

1. General description

The 74LVC245A; 74LVCH245A is an 8-bit transceiver with 3-state outputs. The device features an

output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs

to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This

feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

•5 V tolerant inputs/outputs for interfacing with 5 V logic

•Wide supply voltage range from 1.2 V to 3.6 V

•CMOS low-power consumption

•Direct interface with TTL levels

•Overvoltage tolerant inputs to 5.5 V

•Bus hold on all data inputs (74LVCH245A only)

•IOFF circuitry provides partial Power-down mode operation

•Complies with JEDEC standard:

•JESD8-7A (1.65 V to 1.95 V)

•JESD8-5A (2.3 V to 2.7 V)

•JESD8-C/JESD36 (2.7 V to 3.6 V)

•ESD protection:

•HBM JESD22-A114F exceeds 2000 V

•MM JESD22-A115B exceeds 200 V

•CDM JESD22-C101E exceeds 1000 V

•Specified from -40 °C to +85 °C and -40 °C to +125 °C

of an Nexperia product can reasonably be expected to result in personal

injury, death or severe property or environmental damage. Nexperia and its

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
