CD74HC157M96

Overview

The CD74HC157M96 is a high-speed CMOS logic quad 2-input multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features surface mount SOIC-16 packaging with 16 pins. The device contains four independent multiplexers, each selecting one of two data inputs based on a common select line. Key electrical parameters include a maximum propagation delay of 30 ns at 5 V and an output current capability of 5.2 mA for both high and low states. It supports an operating temperature range from -55 °C to +125 °C.

Feature Summary

• Provides four independent 2-to-1 data selection paths controlled by a single common select input.
• Utilizes high-speed CMOS technology to ensure fast switching speeds and low power consumption.
• Features robust output drive capabilities suitable for interfacing with various digital loads.

Applications

• Data routing in digital communication systems
• Signal selection in microprocessor-based control circuits
• Address/data bus switching in embedded systems

Procurement Notes

Verify the specific suffix M96 against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with system voltage levels between 2 V and 6 V. Confirm RoHS compliance status through the latest component documentation before integration.

Selection Notes

Select this component when multiple independent signal sources require switching to a single destination using a common control line. The HC series offers a balance of speed and power efficiency. Verify that the required propagation delay meets the system timing constraints and that the output current requirements do not exceed the specified limits.

Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC series is widely used in general-purpose digital applications due to its compatibility with standard TTL logic levels while offering improved noise immunity and lower power dissipation compared to older LS or S series counterparts.

Replacement Considerations

Compatible substitutes include SN74HC157 variants from other manufacturers such as NXP or ON Semiconductor, provided they match the SOIC-16 package and electrical characteristics. Verify pinout compatibility and logic function equivalence before substitution.
