Overview
The SN74LV157APWR is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments SN74LV157A series. 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 at 25°C. It provides latch-up performance exceeding 100 mA per JESD 78, Class II standards. The component is housed in a 16-pin TSSOP package.
Feature Summary
- Operates with supply voltages ranging from 2 V to 5.5 V
- Inputs accept voltages up to 5.5 V for compatibility
- Provides high-speed data 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 ordering suffix 'PW' confirms the TSSOP-16 package type before procurement. Confirm RoHS compliance status and lead finish details via the manufacturer's current orderable addendum. Ensure the active production status is validated against the latest datasheet revision history to avoid obsolete variants.
Selection Notes
Select this component when a quadruple multiplexer is required for systems operating between 2 V and 5.5 V. The 5.5 V tolerant inputs allow direct interfacing with higher voltage logic without level shifting. Consider the 16-pin TSSOP footprint for space-constrained surface-mount designs requiring multiple independent data selectors.
Part Context
This part belongs to the SN74LV157A family of quadruple 2-line to 1-line data selectors. The family includes various package options such as SSOP, TVSOP, SOIC, and SOP. The 'A' designation indicates an enhanced version of the original LV157, offering improved electrical characteristics and broader operational specifications compared to legacy counterparts.
