Overview
The SN74LV157APWG4 is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, housed in a 16-pin TSSOP package. It operates within a supply voltage range of 2 V to 5.5 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 7.5 ns at 5 V and includes an active-low output strobe (G) input. It provides true non-inverted data outputs and supports latch-up performance exceeding 100 mA per JESD 78, Class II.
Feature Summary
- Operates with a wide supply voltage range from 2 V to 5.5 V
- Inputs accept voltages up to 5.5 V for interfacing compatibility
- Includes an active-low output strobe control input
- Provides true non-inverted data selection across four channels
Applications
- Servers
- LED Displays
- Network Switches
- Telecom Infrastructure
- Motor Drivers
Procurement Notes
Verify the specific ordering suffix 'G4' indicates RoHS compliance and lead-free material composition as defined by Texas Instruments standards. Confirm the package type corresponds to the PW drawing for TSSOP-16 dimensions. Ensure the component status is checked against the latest TI product folder to confirm availability and production lifecycle stage before finalizing procurement plans.
Selection Notes
Select this component when a quadruple multiplexer with 5.5 V tolerant inputs is required for mixed-voltage systems. The LV series offers low power consumption suitable for battery-operated devices. Verify that the operating temperature range of -40°C to 85°C meets the environmental requirements of the target application board design.
Part Context
This part belongs to the SN74LV157A family of quadruple 2-line to 1-line data selectors. The 'PW' suffix denotes the TSSOP-16 package variant. The 'G4' suffix typically signifies Green/RoHS-compliant manufacturing. It serves as a digital switch controlled by a single select line to route one of two data sources to four parallel outputs.

FAQ
What is the function of the G pin?
The G pin is an active-low output strobe. When G is high, all outputs are forced low regardless of the select or data inputs.
Can this device interface with 5 V logic?
Yes, the inputs accept voltages up to 5.5 V, allowing direct interfacing with 5 V logic devices even if the device itself operates at lower voltages.
