SN74F157ADR

Overview

The SN74F157ADR is a quad 2-input data selector/multiplexer from the Texas Instruments 74F series. It features four independent multiplexers in a single 16-pin SOIC package. The device operates on a single power supply ranging from 4.5 V to 5.5 V. It provides high-speed performance with a propagation delay of 3.1 ns. The component supports surface-mount installation and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexers for parallel data routing
• Delivers high-speed signal switching with low propagation delay characteristics
• Compatible with standard 5 V logic systems via dedicated voltage supply requirements

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Signal selection in test and measurement equipment

Procurement Notes

Verify the specific suffix 'ADR' confirms the SOIC-16 surface mount package and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the design accommodates the specified 4.5 V to 5.5 V operating voltage range and thermal dissipation limits for the chosen application environment.

Selection Notes

Select this component when high-speed switching is required alongside compact surface-mount packaging. The 74F series offers faster performance than standard 74LS counterparts but consumes more power. Consider the 16-SOIC footprint constraints and verify that the system voltage aligns strictly with the 5 V nominal requirement for optimal noise margins.

Part Context

This part belongs to the widely adopted 74F (Fast) logic family, known for superior speed compared to earlier TTL standards. The SN74F157A variant serves as a foundational building block for complex digital logic circuits requiring multiple data paths. Its standardized pinout ensures compatibility across various legacy and modern electronic designs.

Replacement Considerations

SN74F157ADRG4 is a verified equivalent part number offering identical electrical specifications and functionality.
