74HCT366PW,118

Overview

The Nexperia 74HCT366PW,118 is a hex inverting buffer/line driver with 3-state outputs controlled by active LOW output enable inputs (OE1 and 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-level input compatibility, clamp diodes on all inputs for overvoltage interfacing, and high noise immunity. It is housed in a 16-lead TSSOP plastic thin shrink small outline package (SOT403-1) designed for surface-mount applications.

Feature Summary

• Provides six independent inverting buffers or line drivers with controllable 3-state outputs
• Features TTL-compatible input levels for direct interface with standard logic systems
• Includes input clamp diodes allowing safe interfacing to voltages exceeding the supply rail using current limiting resistors

Applications

• High-speed data bus buffering and signal inversion
• Line driving for communication interfaces requiring 3-state isolation
• TTL-to-CMOS level translation circuits utilizing inverting functionality

Procurement Notes

Verify that the specific order code matches the HCT logic family requirements, as HC variants differ in input thresholds. Confirm the PW suffix corresponds to the TSSOP16 package format required for your PCB footprint. Ensure design specifications align with the 4.5 V to 5.5 V operating voltage range defined in the recommended operating conditions.

Selection Notes

Select this component when inverting logic functions are required alongside tri-state bus control capabilities. The HCT series is appropriate for systems powered by 5 V supplies where TTL input thresholds must be respected. Consider the TSSOP16 package dimensions if space constraints preclude larger SOIC footprints while maintaining lead pitch compatibility.

Part Context

This part belongs to the 74HCT366-Q100 automotive-grade family, though the PW,118 variant specifically denotes the commercial-grade production version. It shares functional equivalence with the non-inverting 74HC365 counterparts but provides inverted outputs. The device complies with JEDEC standards JESD8C and JESD7A for CMOS low power dissipation and noise immunity characteristics.

Replacement Considerations

Direct functional substitutes include the 74HC366PW and 74HCT366PW from Nexperia, differing only in logic family voltage thresholds. Cross-manufacturer equivalents such as the SN74HCT366N or MC74HCT366ADR2G offer identical pinouts and logical operations, provided package variations are accommodated.
