TC74HC153AF(EL,F)

Overview

The TC74HC153AF(EL,F) is a dual 4-input multiplexer from the Toshiba 74HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and features a propagation delay of 15 ns. The device utilizes CMOS technology and is housed in a 16-pin SOP package. It supports surface mount installation and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual independent 4-to-1 data selection capability
• High-speed signal routing with low propagation delay
• Wide operational voltage compatibility for diverse logic levels

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor interfaces
• Signal switching in test and measurement equipment

Procurement Notes

Verify the specific suffix EL,F against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the ordering code aligns with the desired tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this component when dual independent multiplexing is required within standard HC logic voltage ranges. Consider the 16-pin SOP footprint for PCB layout constraints. Verify that the 15 ns propagation delay meets the timing specifications of the target application circuit.

Part Context

This part belongs to the Toshiba 74HC series, which offers performance compatible with Low-power Schottky TTL. The TC74HC153AF variant specifically provides two separate multiplexer circuits in a single package, optimizing board space compared to using individual single multiplexer ICs.

Replacement Considerations

Compatible substitutes include the MC74HC153ADWR2G from onsemi. Verify pin compatibility and electrical parameters before substitution.
