MC74HC365ADT

Overview

The MC74HC365ADT 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 a TSSOP-16 package. Key electrical parameters include a propagation delay of 20 ns, static current of 4 uA, and output currents of -7.8 mA (high) and 7.8 mA (low). It functions reliably across an operating temperature range of -55 C to +125 C.

Feature Summary

• Hex configuration with three-state non-inverting outputs
• Dual enable input control for high-impedance state management
• Wide operating voltage compatibility from 2 V to 6 V
• ESD protection circuits integrated on all inputs

Applications

• Bus-oriented memory and signal driving
• Clock distribution networks
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'DT' against official datasheets to confirm the exact package variant and tape/reel specifications. Ensure the order matches the required TSSOP-16 form factor and check RoHS compliance documentation for material declarations. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a hex buffer with tri-state capability is required for bus applications. The HC series offers CMOS low power consumption compared to older TTL standards. Verify that the 2 V to 6 V supply range aligns with the system design and that the TSSOP-16 package fits the PCB layout constraints. Consider the 20 ns propagation delay for timing requirements.

Part Context

This part belongs to the MC74HC365A family of advanced high-speed CMOS devices. It is functionally compatible with the standard 74 series 365 but utilizes silicon gate C2MOS technology for improved performance. The device is designed for low power dissipation while maintaining high noise immunity, making it suitable for various digital logic applications requiring signal buffering and isolation.

Replacement Considerations

MC74HC365ADTR2G: Verified alternative from onsemi with identical logical function and pinout, differing primarily in packaging format (reel vs. cut tape or tube variations).
