SN74F153NSR

Overview

The SN74F153NSR is a dual 1-of-4 data selector/multiplexer from Texas Instruments, part of the F/FAST logic series. It features two independent multiplexers in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0 °C to 70 °C. It utilizes bipolar logic technology with non-inverting outputs.

Feature Summary

• Integrates two independent 4-line to 1-line data selectors within a single package
• Provides high-speed signal switching capabilities suitable for digital data processing
• Features standard TTL-compatible inputs and outputs

Applications

• Digital data routing and selection circuits
• Address decoding applications
• General-purpose signal switching in industrial control systems

Procurement Notes

Verify the specific suffix 'NSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC package dimensions align with the target PCB footprint. Ensure the commercial temperature grade (0°C to 70°C) meets the operational environmental requirements of the final system design before procurement.

Selection Notes

Select this component when dual independent multiplexing functionality is required in a compact surface-mount form factor. The F/FAST series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the 16-pin SOIC package constraints and verify compatibility with existing 5V logic families in the circuit design.

Part Context

This component belongs to the SN74F153 family of dual 1-of-4 multiplexers manufactured by Texas Instruments. The 'N' designation indicates a plastic small-outline package, while 'SR' typically denotes reel-based packaging. It is part of the broader SN74xx logic product line designed for various digital logic applications.

Replacement Considerations

The SN74F153DRG4 is a documented equivalent variant from Texas Instruments featuring similar dual multiplexer functionality. Verify pinout compatibility and electrical specifications before substitution.
