74HCT366PW-Q100,11

Overview

The 74HCT366PW-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 inputs for overvoltage interfacing, and high noise immunity. Outputs assume a high-impedance OFF-state when enabled inputs are HIGH.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Inverting outputs with 3-state control via dedicated enable pins
• TTL-compatible input logic levels for direct interface with TTL systems
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Automotive electronic systems requiring qualified logic buffers
• Bus line driving applications with inverting signal requirements
• Systems utilizing mixed 5 V and 3.3 V logic interfaces
• Industrial control environments operating at extended temperatures

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the automotive grade qualification aligns with project reliability standards. Ensure input voltage levels are compatible with the TTL thresholds specified for the HCT series. Check for any recent datasheet revisions affecting pin definitions or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when inverting functionality is required alongside 3-state bus isolation. The HCT series is appropriate for designs needing TTL input compatibility rather than CMOS levels. Consider the TSSOP16 package constraints regarding thermal dissipation and PCB space. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V recommended operating conditions.

Part Context

This part belongs to the Nexperia 74HC(H)T366-Q100 family of hex buffers. It is functionally identical to the non-inverting 74HC365-Q100 but provides inverted outputs. The product is designed for robust performance in demanding environments, offering low power dissipation and high noise immunity typical of CMOS technology.

Replacement Considerations

The 74HC365PW-Q100,118 serves as a functional substitute if non-inverting outputs are acceptable instead of inverting ones. Both parts share the same package, pinout, and automotive qualification status.
