1. General description
The 74LVC1G3157 is a high-performance, low-power, low-voltage, Si-gate CMOS device
that provides superior performance to most advanced CMOS compatible TTL families.
The 74LVC1G3157 provides one analog multiplexer/demultiplexer with one digital select
input (S), two independent inputs/outputs (B1 and B2) and a common input/output (A).
2. Features
■Wide supply voltage range from 1.65 V to 5.5 V
■Very low ON-resistance:
◆7.5 Ω (typical) at VCC = 2.7 V
◆6.5 Ω (typical) at VCC = 3.3 V
◆6Ω (typical) at VCC =5V
■Break-before-make switching
■High noise immunity
■ESD protection:
◆HBM EIA/JESD22-A114-B exceeds 2000 V
◆MM EIA/JESD22-A115-A exceeds 200 V
■CMOS low-power consumption
■Latch-up performance meets requirements of JESD 78 Class I
■Direct interface with TTL levels
■Control input accepts voltages up to 5 V
■Multiple package options
■Specified from −40 °C to +85 °C and from −40 °C to +125 °C

9. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
10. Recommended operating conditions
[1] To avoid drawing VCC current out of terminal A when switch current flows in terminal Bn, the voltage drop
across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal A, no VCC
current will flow out of terminal Bn. In this case, there is no limit for the voltage drop across the switch.
[2] Applies to control signal levels.

17. Data sheet status
[1] Please consult the most recently issued data sheet before initiating or completing a design.
[2] The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at
URL http://www.semiconductors.philips.com.
[3] For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
18. Definitions
Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
