SN74ALS158NG4

Overview

The SN74ALS158NG4 is a quad 1-of-2 data selector/multiplexer manufactured by Texas Instruments. It belongs to the ALS logic series and features four independent multiplexers within a single package. The device operates with a supply voltage range of 4.5 V to 5.5 V and has a propagation delay of 14 ns. It is housed in a 16-pin PDIP package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Integrates four independent 1-of-2 data selectors for efficient signal routing
• Utilizes Advanced Low-power Schottky (ALS) technology for high-speed performance
• Provides standard TTL-compatible inputs and outputs

Applications

• Data routing in digital systems
• Signal selection circuits
• Multiplexing applications requiring multiple channels

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current documentation to confirm compliance details and availability status, as suffixes can indicate environmental or packaging variations that affect procurement specifications.

Selection Notes

Select this component when designing circuits requiring multiple independent data paths with low power consumption and moderate speed. Ensure the design accommodates the 16-pin DIP form factor and the specified voltage and temperature constraints for reliable operation.

Part Context

This part is part of the SN74ALS158 family, which includes variants like the SN74ALS158D and SN74ALS157ANSR. While sharing similar functional characteristics as quad multiplexers, differences exist in package types such as SOIC or SOIC-Narrow, and reel versus tube packaging configurations.

Replacement Considerations

Compatible substitutes include the SN74ALS158D and SN74ALS157ANSR. Verify pinout compatibility and electrical parameters before substitution.
