CD74HC244M96E4

Overview

The CD74HC244M96E4 is a high-speed CMOS logic device featuring non-inverting octal buffers and line drivers with three-state outputs. It operates within a supply voltage range of 2 V to 6 V, drawing a maximum static current of 8 uA and a working power supply current of 80 uA. The component supports output currents of -7.8 mA at high levels and 7.8 mA at low levels. Propagation delays are specified as 110 ns at 2 V, 22 ns at 4.5 V, and 19 ns at 6 V. It functions reliably across an extended temperature range from -55 C to +125 C and utilizes a 20-SOIC surface-mount package.

Feature Summary

• Provides eight unidirectional signal paths with independent active-low output enables for precise bus management.
• Delivers high-speed performance suitable for complex digital systems through optimized CMOS architecture.
• Maintains stable operation across wide industrial temperature extremes without compromising electrical characteristics.

Applications

• Memory address buffering in computer systems
• Clock distribution networks
• Bus-oriented transmissions

Procurement Notes

Verify the specific M96 suffix against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and exact pinout configurations. Ensure compatibility with existing PCB footprints by cross-referencing the SOIC-20 mechanical dimensions. Confirm RoHS compliance status directly with the supplier or original datasheet before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust octal buffering with tri-state control capabilities. The extended temperature rating makes it suitable for harsh environments where standard commercial grade parts may fail. Consider the propagation delay variations relative to the operating voltage to ensure timing margins meet system requirements.

Part Context

This part belongs to the Texas Instruments CD74HC244 series of high-speed CMOS logic devices. It serves as a variant within the broader family of octal buffers and line drivers, distinguished by its specific packaging and environmental ratings. The series is widely recognized for providing reliable signal integrity in digital logic applications.

Replacement Considerations

Direct substitutes include CD74HC244M and SN74HC244DWRE4, provided pinouts and electrical parameters match the design requirements. Verify that alternative packages maintain identical thermal and mechanical constraints for seamless integration.
