MC74HC365AD

Overview

The MC74HC365AD is a hex bus buffer manufactured by onsemi, belonging to the HC logic series. 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 surface mount installation in an SOIC-16 package. Key electrical parameters include a propagation delay of 20 ns, high-level output current of -7.8 mA, low-level output current of 7.8 mA, and static current of 4 uA. It functions across a temperature range of -55 C to +125 C.

Feature Summary

• Hex configuration with three-state outputs for bus-oriented communication
• Dual enable inputs control all six buffers simultaneously
• Non-inverting signal transmission with high noise immunity
• Wide operating voltage range supporting various logic families

Applications

• Bus-oriented memory and address drivers
• Clock drivers
• Bus holding registers

Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and tape/reel specifications. Ensure the order matches the required logic family (HC vs HCT) and voltage compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple buffered outputs with tri-state capability. The HC series offers higher speed than standard 74LS logic while maintaining CMOS power efficiency. Consider the 2V to 6V operating range for flexibility in different supply environments compared to fixed-voltage alternatives.

Part Context

This part belongs to the MC74HC365A series of hex bus buffers. It is functionally compatible with other 74HC365 variants from different manufacturers but may differ in packaging or specific electrical characteristics. The 'AD' suffix typically denotes the SOIC-16 package variant offered by onsemi.

Replacement Considerations

MC74HC365ADR2G is a parameter-equivalent alternative available from onsemi, differing primarily in packaging format.
