74HCT365D/AUJ

Overview

The 74HCT365D is a hex buffer and line driver manufactured by Nexperia, featuring six non-inverting outputs with three-state control. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device includes two active-low output enable inputs (OE1 and OE2) that manage the high-impedance OFF-state. Packaged in a 16-lead SO plastic small outline package (SOT109-1), it supports an ambient operating temperature from -40 °C to +125 °C.

Feature Summary

• Provides six non-inverting buffered outputs controlled by dedicated active-low enable inputs for tri-state management.
• Accepts TTL logic level inputs while maintaining CMOS low power dissipation characteristics.
• Includes input clamp diodes to allow interfacing with voltages exceeding the supply rail using current limiting resistors.

Applications

• High noise immunity signal buffering
• Driving bus lines with three-state capability
• Line drivers requiring TTL-to-CMOS translation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the exact package type and temperature grade. Confirm whether the requested part number corresponds to the standard SO16 package or other available variants listed in the official datasheet.

Selection Notes

Select this component when a hex buffer with three-state outputs and TTL-compatible inputs is required. Ensure the application environment stays within the specified -40 °C to +125 °C temperature range and utilizes a 4.5 V to 5.5 V supply voltage.

Part Context

This component belongs to the 74HCT series of logic devices, designed for compatibility with TTL logic levels while utilizing CMOS technology. The 74HCT365 variant specifically provides hex buffering with tri-state functionality, distinct from the HC series which uses CMOS input levels.

Replacement Considerations

The 74HCT365PW is documented as a similar alternative offering the same logical function in a TSSOP16 package.
