CD74HC244EE4

Overview

The CD74HC244EE4 is a high-speed CMOS logic octal buffer and line driver featuring non-inverting outputs with three-state capability. It operates within a supply voltage range of 2 V to 6 V and supports an extended operating temperature range from -55°C to +125°C. The device utilizes a 20-pin PDIP package and includes two active-low output enables for independent control of the eight channels.

Feature Summary

• Non-inverting octal buffering with three-state outputs
• Two active-low output enable controls
• High-current bus driver outputs

Applications

• Bus-oriented transfers
• Clock drivers
• Buffered registers

Procurement Notes

Verify the specific 'E' suffix indicates the PDIP-20 package configuration and confirm the 'E4' designation aligns with current lead-free manufacturing standards. Cross-reference the manufacturer's latest orderable addendum to ensure the part remains in active production status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring wide voltage operation between 2 V and 6 V or environments demanding temperatures down to -55°C. Ensure the application benefits from the non-inverting logic function and requires the isolation provided by the dual active-low output enables.

Part Context

This device belongs to the Texas Instruments HC series of high-speed CMOS logic, designed to replace lower-performance technologies like LSTTL while offering significant power reduction. It shares identical pinouts with related variants such as the CD74HC240 and CD74HC241, facilitating flexible design implementations.
