SN74LV157ADG4

Overview

The SN74LV157ADG4 is a quadruple 2-line to 1-line data selector/multiplexer from the LV logic series. It operates within a supply voltage range of 2 V to 5.5 V and features inputs that accept voltages up to 5.5 V. The device provides a maximum propagation delay of 7.5 ns at 5 V. It includes latch-up performance exceeding 100 mA per JESD 78, Class II, and typical output ground bounce of 2 V at VCC with TA = 25°C.

Feature Summary

• Operates across a wide supply voltage range from 2 V to 5.5 V
• Inputs tolerate voltages up to 5.5 V for flexible interfacing
• Provides high-speed signal selection with low propagation delay
• Features robust latch-up protection exceeding industry standards

Applications

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

Procurement Notes

Verify the specific package type and suffix against the manufacturer's current orderable addendum. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure the ordering information matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when designing systems requiring quad multiplexing with broad voltage compatibility. The LV series supports operation down to 2 V, making it suitable for mixed-voltage environments. Verify that the input voltage levels align with the source logic family to ensure proper signal integrity without additional level shifting circuitry.

Part Context

This part belongs to the SN74LV157A family of quadruple 2-line to 1-line data selectors. The 'DG' suffix indicates a TVSOP-16 package variant. The device functions as a true data selector, routing one of two sources to four outputs based on address select inputs and an active-low strobe signal.
