SN74HC151D

Overview

The SN74HC151D is an 8-to-1 line data selector/multiplexer from Texas Instruments, belonging to the HC logic series. It features eight data inputs and a single output, housed in a 16-pin SOIC-Narrow package. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation. It functions across a temperature range of -40°C to +85°C with a typical propagation delay of 63 ns.

Feature Summary

• Provides complete binary decoding for selecting one of eight data sources
• Includes strobe input functionality to force standard output low and inverted output high when active

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to potential availability of counterfeit parts. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions maintain moisture sensitivity level standards before soldering. Review datasheet specifications for electrical characteristics relevant to specific circuit requirements.

Selection Notes

Select this component for applications requiring efficient routing of multiple digital signals to a single destination. Consider the HC logic family compatibility with existing system voltage levels. Evaluate the physical footprint constraints against the SOIC-Narrow package dimensions. Assess thermal management needs based on the specified operating temperature range.

Part Context

This multiplexer belongs to the broader SN74HC151 family, which includes variants like SN74HC151DG4 and SN74HC151PWR. These components share identical logical functionality but differ in packaging styles such as TSSOP or tube packaging configurations. The family serves as a standard solution for digital signal routing in consumer and industrial electronics.
