CD74HCT367E

Overview

The CD74HCT367E is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six non-inverting buffers with three-state outputs, housed in a 16-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 25 ns at 4.5 V, low-level output current of 4 mA, and high-level output current of -4 mA. Static current is limited to 8 uA, while operating supply current reaches 80 uA. The component supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides six independent non-inverting signal buffering paths for data transmission applications.
• Integrates three-state output control to enable bus-oriented communication and system isolation.
• Utilizes HCT CMOS technology to ensure compatibility with standard TTL logic input levels.

Applications

• Bus-oriented systems requiring signal isolation and driving capability
• Clock distribution networks for timing synchronization
• Memory address drivers for digital storage interfaces

Procurement Notes

Verify the specific suffix E indicates the PDIP-16 through-hole package configuration when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation prior to integration. Ensure the procurement channel provides valid traceability for the Texas Instruments brand. Cross-reference the full part number against distributor catalogs to avoid confusion with surface-mount variants like the MG4 or NSR versions.

Selection Notes

Select this component when interfacing between TTL-compatible sources and CMOS loads requiring high drive strength. The HCT series ensures direct compatibility with 5V logic families without level shifting. Consider the PDIP-16 package for prototyping or applications necessitating through-hole mounting. Evaluate the 4.5V to 5.5V operating window against the target system power rails to ensure reliable operation under all conditions.

Part Context

This device belongs to the CD74HCT367 family of hex buffers. It serves as a functional equivalent to other industry-standard hex buffer ICs but is distinguished by its specific Texas Instruments manufacturing process and PDIP packaging. The HCT designation signifies high-speed CMOS technology optimized for 5V operation with TTL-compatible inputs, differentiating it from standard HC or AC series counterparts.

Replacement Considerations

Public confirmed substitute part numbers: SN74HC367NSR, CD74HC367, CD74HCT367MG4.
