SN74HC151ANSG4

Overview

The SN74HC151ANSG4 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 within a supply voltage range of 2 V to 6 V and features low power consumption with a maximum ICC of 80 μA. It includes standard (Y) and inverted (W) outputs, with a typical propagation delay of 13 ns. The component is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Provides complete binary decoding for selecting one of eight data inputs
• Features both standard and inverted outputs for flexible logic interfacing
• Operates with low power consumption suitable for battery-powered applications
• Includes enable input that forces outputs to specific states when inactive

Applications

• Data source selection in digital systems
• Parallel-to-serial data conversion
• Boolean function generation
• Demultiplexing operations

Procurement Notes

Verify the exact suffix 'NSG4' against official Texas Instruments documentation to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring an 8-channel multiplexer with HC logic speed and low power consumption. Verify that the 2 V to 6 V operating voltage range aligns with your system's power supply. Consider the 16-pin SOIC-Narrow package constraints for PCB layout. Ensure the input current requirements are met by your driving circuitry given the 1 μA maximum input current specification.

Part Context

This part belongs to the SN74HC151 family of 8-line to 1-line data selectors/multiplexers manufactured by Texas Instruments. It is part of the broader 74HC logic series, designed for high-speed CMOS operation. The device serves as a fundamental building block for data routing and selection in digital electronics, offering a balance of speed and power efficiency.

Replacement Considerations

Compatible substitutes include the SN74HC151DR and SN74HC151D from Texas Instruments, which share identical logical functions and pinouts. Other manufacturers may offer equivalent parts under different part numbers, but verification of electrical parameters and package dimensions is required.
