SN74F153N

Overview

The SN74F153N 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 single package, each selecting one of four data inputs based on address lines. The device operates within a temperature range of 0°C to 70°C and utilizes a 16-pin Dual In-Line Package (DIP). It supports standard TTL voltage levels and provides true outputs for digital data routing applications.

Feature Summary

• Dual independent 4-line to 1-line multiplexing capability
• High-speed silicon-gate CMOS technology for fast switching
• Standard DIP packaging for through-hole mounting

Applications

• Digital data processing systems
• Data routing and selection circuits
• Address decoding applications

Procurement Notes

Verify the specific suffix 'N' indicates the PDIP package variant when ordering. Confirm RoHS compliance status as per current manufacturer documentation. Ensure the operating environment remains within the specified 0°C to 70°C commercial temperature range. Check for equivalent lead-free variants if required by assembly standards.

Selection Notes

Select this component for applications requiring dual 4-to-1 multiplexing with high-speed performance. Compare against HC or HCT series if lower power consumption is prioritized over speed. Ensure input voltage levels match the system's logic family requirements. Verify pin compatibility with existing PCB footprints before integration.
