SN74HC153DE4

Overview

The SN74HC153DE4 is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It belongs to the 74HC series of high-speed CMOS logic devices, designed for surface-mount applications in SOIC-16 packages. The component features two independent multiplexers, each selecting one of four data inputs based on three address lines. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. The device provides balanced propagation delays and low power consumption typical of HC technology.

Feature Summary

• Dual independent 4-to-1 data selection capability within a single package
• High-speed CMOS construction ensuring low power dissipation
• Wide supply voltage compatibility ranging from 2 V to 6 V
• Surface-mount packaging optimized for automated assembly processes

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Signal switching in test and measurement equipment
• Input selection for analog-to-digital converter front ends

Procurement Notes

Verify the specific suffix DE4 corresponds to the SOIC-16 narrow package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the supplier provides traceability for automotive or industrial grade requirements if applicable. Check for obsolescence notices as Texas Instruments may update product lifecycles without immediate replacement announcements.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required in space-constrained surface-mount designs. Compare against SN74HCT153 variants if TTL-compatible input levels are necessary instead of standard CMOS levels. Evaluate propagation delay specifications against system timing constraints. Consider package availability and thermal performance for high-density PCB layouts requiring multiple logic functions.

Part Context

The SN74HC153DE4 is part of Texas Instruments' extensive 74HC family of high-speed CMOS logic integrated circuits. This family serves as a modern replacement for older transistor-transistor logic (TTL) components, offering improved speed and lower power consumption. The DE4 designation specifically identifies the SOIC-16 surface-mount package variant with lead-free and halogen-free attributes compliant with international environmental standards.

Replacement Considerations

SN74HC153DR is a direct pin-compatible alternative from Texas Instruments in the same logic family. CD74HC153M96 from Texas Instruments offers identical functionality in a similar SOIC-16 package. Verify electrical characteristics and package dimensions before substituting with non-TI manufacturers to ensure signal integrity.
