CD74HCT244M96

Overview

The CD74HCT244M96 is a high-speed CMOS octal buffer and line driver manufactured by Texas Instruments. It features eight non-inverting buffers with three-state outputs, designed for high-capacitance loading applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. It utilizes a 20-pin SOIC package. Key electrical characteristics include a maximum static current of 8 µA, low-level output current of 6 mA, and high-level output current of -6 mA. Propagation delay is specified at 28 ns.

Feature Summary

• Provides eight non-inverting buffer channels with independent three-state control for efficient bus-oriented architectures.
• Features Schmitt-trigger action on all inputs to ensure clean transitions and noise immunity in noisy environments.
• Designed for high-capacitance loading capabilities, making it suitable for driving heavy loads directly.

Applications

• Memory module address and data bus drivers
• Clock distribution circuits requiring signal conditioning
• Industrial control systems operating in harsh thermal environments

Procurement Notes

Verify the specific suffix 'M96' against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with 5V logic levels, as this HCT variant does not support lower voltage ranges like 3.3V or 2.5V. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designing systems requiring robust signal buffering with noise tolerance provided by Schmitt triggers. It is appropriate for applications needing wide temperature stability up to 125°C. Consider the 20-SOIC footprint for surface-mount assembly constraints. Verify that the 5V-only supply requirement aligns with the system power architecture.

Part Context

This part belongs to the Texas Instruments CD74HCT series, which combines high-speed CMOS performance with standard TTL-compatible input thresholds. The '244' designation indicates an octal buffer configuration, while the 'M96' suffix typically denotes a specific reel quantity and packaging format for automated assembly processes.

Replacement Considerations

CD74HC244M96: Compatible HC series alternative with wider voltage range but lacks Schmitt trigger inputs.
