M74HC365YTTR

Overview

The M74HC365YTTR is a hex bus buffer with three-state outputs manufactured by STMicroelectronics. It operates within a supply voltage range of 2 V to 6 V and features six non-inverting channels in a 16-TSSOP package. Key electrical parameters include a propagation delay of 10 ns at 6 V, maximum static current of 4 μA, and output drive currents of ±7.8 mA. The device supports an operating temperature range from -40 °C to +125 °C and meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Hex bus buffer architecture with three-state outputs controlled by two enable inputs
• Advanced high-speed CMOS fabrication using silicon gate C2MOS technology
• Integrated protection circuits against static discharge and transient excess voltage on all inputs

Applications

• Automotive electronic systems requiring AEC-Q100 qualified logic components
• High-speed data buffering in consumer electronics
• Industrial control systems needing wide operating temperature tolerance

Procurement Notes

Verify the specific suffix 'YTTR' corresponds to the TSSOP-16 package and reel packaging configuration. Confirm AEC-Q100 automotive qualification status matches project requirements. Ensure input voltage levels align with the HC series specifications rather than HCT or other variants. Check RoHS compliance documentation for final assembly verification.

Selection Notes

Select this component when a wide 2 V to 6 V supply range is required compared to fixed 5 V logic families. Choose the HC series over HCT if lower power consumption and higher noise immunity are prioritized over TTL-compatible input thresholds. The TSSOP-16 package offers a compact surface-mount solution suitable for space-constrained designs.

Part Context

This part belongs to the M74HC365 series of hex bus buffers. It is functionally compatible with the standard 74HC365 logic family but utilizes STMicroelectronics' specific C2MOS process technology. The device serves as a direct replacement for legacy 74-series buffers while offering improved speed and lower power dissipation characteristics.

Replacement Considerations

MC74HC365ADTR2G from onsemi is a documented parameter-equivalent substitute.
