SN74ALS151DRE4

Overview

The SN74ALS151DRE4 is an Advanced Low-Power Schottky (ALS) TTL 8-line-to-1-line data selector or multiplexer manufactured by Texas Instruments. It features eight data inputs, three enable inputs, and complementary outputs in a 16-pin SOIC package. The device operates within a standard 4.5 V to 5.5 V supply voltage range and supports a commercial temperature range of 0 °C to 70 °C. Designed for high-speed digital applications, it provides fast propagation delays characteristic of the ALS logic family while maintaining low power consumption.

Feature Summary

• Provides 8-to-1 data selection capability with complementary outputs
• Features three enable inputs for flexible control and system integration
• Utilizes Advanced Low-Power Schottky technology for optimized speed and power efficiency

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Waveform generation circuits

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the operating environment remains within the specified 0 °C to 70 °C commercial temperature range to maintain performance specifications.

Selection Notes

Select this component when requiring high-speed switching with lower power dissipation than standard LS TTL. Verify that the 4.5 V to 5.5 V supply voltage aligns with your system design. Consider the three enable inputs for complex gating requirements compared to devices with fewer control lines.

Part Context

This part belongs to the SN74ALS151 series of multiplexers from Texas Instruments. It is part of the broader 74xx logic family, specifically utilizing Advanced Low-Power Schottky technology. The series offers a balance between processing speed and power efficiency suitable for general-purpose digital logic applications.

Replacement Considerations

Check for direct equivalents such as the SN74ALS151DR. Verify compatibility with other 8-to-1 multiplexers in the ALS family. Ensure pinout and electrical characteristics match before substituting.
