SN74LV157ADBR

Overview

The SN74LV157ADBR is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. 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. It is housed in a 16-pin SSOP package with dimensions of 6.2 mm by 5.3 mm. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Provides four independent 2-to-1 multiplexing channels for data selection
• Supports wide supply voltage operation from 2 V to 5.5 V
• Inputs tolerate 5.5 V signals regardless of the VCC level
• Includes an active-low output strobe (G) pin for enabling or disabling outputs

Applications

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

Procurement Notes

Verify that the component matches the SN74LV157ADBR designation, specifically confirming the DB (SSOP) package code. Ensure the orderable part number aligns with the active production status listed in the manufacturer's documentation. Confirm RoHS compliance and lead finish specifications match project requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple independent data paths with low-voltage compatibility. The LV series offers high noise immunity and fast switching speeds suitable for digital logic applications. Consider the 16-pin SSOP footprint constraints during PCB layout planning to ensure adequate spacing and thermal management for the selected package type.

Part Context

This device belongs to the SN74LV157A family of quadruple multiplexers. It is designed for general-purpose digital signal routing in CMOS technology. The 'LV' designation indicates low-voltage operation compatible with various logic families. The specific 'DB' suffix denotes the Small Outline Shrink Package variant used for surface-mount assembly.

Replacement Considerations

Check the Package Option Addendum for other active variants like SN74LV157ADR or SN74LV157APWR. Verify pinout compatibility and electrical characteristics against the original design requirements before substituting.
