CD74HC365M

Overview

The CD74HC365M is a hex buffer and line driver manufactured by Texas Instruments, belonging to the HC logic family. It features six non-inverting buffers with three-state outputs controlled by two enable inputs. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to 85°C. Key electrical characteristics include a maximum propagation delay of 20 ns at 6 V and a maximum quiescent current of 80 µA.

Feature Summary

• Hex configuration providing six independent non-inverting buffer channels
• Three-state output capability allowing high-impedance disconnection for bus driving
• Dual low-active enable inputs (G1 and G2) controlling all outputs simultaneously
• CMOS technology ensuring low static power consumption and wide voltage operation

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Bidirectional data bus transceivers
• Line drivers for signal transmission

Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and environmental compliance. Ensure the component matches the required voltage and temperature specifications for the target application. Confirm availability status as older variants may be discontinued or subject to change notices.

Selection Notes

Select this component when a hex buffer with three-state outputs is required for bus applications. Consider the HC series for compatibility with standard 5 V logic systems while supporting lower voltages down to 2 V. Verify that the SOIC-16 package fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the SN74HC/CD74HC/SM74HC365 family of hex buffers and line drivers. It is functionally compatible with other 74HC365 variants from different manufacturers, sharing pinouts and logical operations. The device is designed for use in general-purpose digital systems requiring buffered signals with tri-state control.

Replacement Considerations

Compatible substitutes include SN74HC365, SN74HCT365, and MC74HC365. Verify voltage levels and package dimensions before substitution. Ensure the replacement maintains the same three-state functionality and enable logic.
