Overview
The SN74LV157ADR is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments LV logic family. 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 typical output ground bounce of 2 V. It provides latch-up performance exceeding 100 mA per JESD 78, Class II standards. The component is housed in a 16-pin SOIC package.
Feature Summary
- Operates across a wide supply voltage range from 2 V to 5.5 V
- Inputs accept voltages up to 5.5 V for flexible interfacing
- Provides high-speed data selection with low propagation delay
- Features robust latch-up protection exceeding standard requirements
Applications
- Servers
- LED Displays
- Network Switches
- Telecom Infrastructure
- Motor Drivers
Procurement Notes
Verify the specific ordering suffix 'DR' corresponds to the SOIC-16 package configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's current orderable addendum. Ensure the active production status aligns with long-term availability requirements before finalizing procurement plans.
Selection Notes
Select this component when a quad multiplexer is required for systems operating between 2 V and 5.5 V. It is suitable for applications needing inputs compatible with 5 V signals while powered by lower voltages. Consider the SOIC-16 package constraints regarding board space and thermal dissipation capabilities during the design phase.
Part Context
This part belongs to the SN74LV157A series of quadruple 2-line to 1-line data selectors. The series is designed for 2 V to 5.5 V operation and includes inverters and drivers to supply full data selection to four output gates. A separate strobe input allows control over data routing functionality.
