CD74HC368E

Overview

The CD74HC368E is a high-speed CMOS logic device manufactured by Harris Corporation, functioning as a hex buffer and line driver. It features six inverting channels with three-state outputs, housed in a 16-pin DIP package. The component operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include output currents of 7.8mA for both high and low states, ensuring robust signal driving capabilities for digital applications.

Feature Summary

• Hex configuration providing six independent inverting buffer channels
• Three-state output capability for bus-oriented systems
• High-speed CMOS technology for efficient digital signal processing

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• Digital signal buffering

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Ensure the specific lot date code aligns with current quality standards. Confirm RoHS compliance status, as older Harris-branded units may not meet modern environmental regulations. Cross-reference datasheet revisions to ensure pinout and electrical specifications match your design requirements exactly.

Selection Notes

Select this component when a hex inverting buffer with three-state control is required. The HC series offers compatibility with standard TTL logic levels while maintaining CMOS power efficiency. Consider the wide operating temperature range for industrial environments. Verify that the 16-pin DIP package fits the available PCB footprint and assembly constraints.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for digital circuit design, specifically for signal inversion and isolation. The device is part of a broader lineage of hex buffers, often compared to non-inverting counterparts like the 74HC244.

Replacement Considerations

Texas Instruments CD74HC368E is the direct successor and functional equivalent. Other compatible parts include the SN74HC368. Verify pin compatibility and electrical parameters before substitution.
