CD74HC365E

Overview

The CD74HC365E is a hex bus driver manufactured by Harris Corporation, belonging to the HC/UH logic series. It features six non-inverting buffers with three-state outputs housed in a PDIP14 package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to 125°C. Key electrical parameters include a maximum low-level output current of 0.006 A and a load capacitance specification of 50 pF.

Feature Summary

• Provides six non-inverting buffer channels for signal driving applications
• Features three-state outputs controlled by enable inputs to manage bus traffic
• Utilizes CMOS technology for high-speed operation with low power dissipation

Applications

• Bus line driving capacity for digital systems
• General-purpose buffering in CMOS logic circuits
• Interface applications requiring three-state control

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Confirm that the specific part number corresponds to the original Harris production run rather than subsequent TI manufacturing. Ensure the package type matches the required PDIP14 configuration for your design constraints.

Selection Notes

Select this component when six independent non-inverting buffers with three-state capability are required. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider the industrial temperature range if the application involves extreme environmental conditions. Verify pin compatibility with existing 74HC family layouts.

Part Context

This component is part of the broader 74HC logic family, which offers high-speed CMOS performance comparable to low-power Schottky TTL. The HC365 variant specifically provides non-inverting buffering, distinguishing it from inverting counterparts like the HC366. It shares functional similarities with other bus drivers in the series but is distinct from latches or multiplexers.

Replacement Considerations

The SN74HC365DE4 from Texas Instruments is a documented equivalent offering similar hex buffer functionality. Other compatible options include the MC74HC365ADR2G from onsemi. Verify pinout and electrical specifications against these alternatives before substitution.
