74HCT366D-Q100,118

Overview

The 74HCT366D-Q100,118 is a hex inverting buffer/line driver with 3-state outputs controlled by active LOW output enable inputs (OE1, OE2). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, clamp diodes on all inputs, and complies with AEC-Q100 Grade 1 qualification for automotive applications.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Inverting outputs with 3-state control via dedicated enable inputs
• TTL input levels compatible with standard logic families
• High noise immunity and latch-up performance exceeding 100 mA

Applications

• Automotive electronic systems requiring robust line driving
• Bus driver applications utilizing 3-state isolation
• Mixed-signal interfaces leveraging input clamp diodes

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the component meets the AEC-Q100 Grade 1 specification for your target environment. Ensure design compatibility with the specified 4.5 V to 5.5 V supply voltage range and operating temperature limits before finalizing procurement.

Selection Notes

Select this component when inverting functionality and 3-state bus isolation are required in automotive or industrial environments. The HCT variant ensures compatibility with TTL logic levels. Verify that the SO16 package fits the PCB layout constraints and thermal requirements for the intended application scope.

Part Context

This part belongs to the Nexperia 74HC(H)T366-Q100 family of hex buffers and line drivers. It is functionally identical to the non-inverting 74HC365-Q100 but provides inverted outputs. The D suffix indicates the SO16 plastic small outline package, distinguishing it from TSSOP variants.

Replacement Considerations

The 74HC365D-Q100,118 serves as a functional substitute if non-inverting outputs are acceptable instead of the inverting configuration provided by the 74HCT366.
