SN74LV157APW

Overview

The SN74LV157APW is a quadruple 2-line to 1-line data selector/multiplexer designed for 2 V to 5.5 V VCC operation. It features inputs that accept voltages up to 5.5 V and a maximum propagation delay of 7.5 ns at 5 V. The device provides latch-up performance exceeding 100 mA per JESD 78, Class II, with typical output ground bounce of 2 V at VCC and TA = 25°C.

Feature Summary

• Operates within a supply voltage range of 2 V to 5.5 V
• Inputs tolerate voltages up to 5.5 V
• Provides high latch-up protection exceeding 100 mA

Applications

• Servers
• LED Displays
• Network Switches
• Telecom Infrastructure
• Motor Drivers

Procurement Notes

Verify the specific package type and tape-and-reel specifications against the manufacturer's current orderable addendum. Confirm RoHS compliance status and lead finish details before finalizing procurement orders to ensure compatibility with assembly processes.

Selection Notes

Select this component when a quadruple multiplexer is required for low-voltage logic applications. Ensure the design accommodates the 2 V to 5.5 V operating range and utilizes the TSSOP-16 package constraints. Verify input voltage levels do not exceed the 5.5 V tolerance limit.
