SN74HC151DT

Overview

The SN74HC151DT is an 8-line to 1-line data selector/multiplexer from the Texas Instruments SN74HC series. It provides complete binary decoding to select one of eight data sources. The device operates with a supply voltage range of 2 V to 6 V and features low input current of 1 μA maximum. It includes standard (Y) and complementary (W) outputs, with a strobe (G) input that disables the device when high. Typical propagation delay is 13 ns at 5 V.

Feature Summary

• Provides complete binary decoding for selecting one of eight data inputs
• Features low input current and wide operating voltage range
• Includes standard and complementary outputs with active-low enable control

Applications

• Data source selection
• Demultiplexing
• Parallel-to-serial conversion
• Boolean function generation

Procurement Notes

Verify the specific package type and tape/reel specifications against the manufacturer's official datasheet for the SN74HC151DT suffix. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes

Select this component for applications requiring 8-channel data routing within the HC logic family. Ensure the system voltage falls within the 2 V to 6 V range. Consider the 13 ns typical propagation delay for timing constraints in high-speed designs.

Part Context

This part belongs to the SN74HC151 family of 8-to-1 multiplexers. It is compatible with other HC-series logic devices. The DT suffix typically indicates a TSSOP-16 package variant, distinct from the DR (SOIC-16) or PWR (TSSOP-16) variants found in distributor listings.

Replacement Considerations

SN74HC151DR: SOIC-16 package variant with identical electrical characteristics. SN74HC151PWR: TSSOP-16 package variant with identical electrical characteristics. Verify pinout compatibility and thermal performance differences between packages.
