74HCT366DB,112

Overview

The 74HCT366DB,112 is a hex inverting buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (OE1, OE2). It belongs to the HCT logic family, accepting TTL-level inputs while operating on CMOS technology. The device provides six independent data paths with inverted outputs. Inputs include clamp diodes for interfacing with voltages exceeding VCC. The component is housed in a 16-lead SSOP package (SOT338-1) and operates within a supply voltage range of 4.5 V to 5.5 V.

Feature Summary

• Hex inverting buffer configuration with three-state outputs
• TTL-compatible input levels for direct interface with digital systems
• Active LOW output enable control via dual OE pins
• Input clamp diodes allow current limiting resistor usage

Applications

• Memory address drivers
• Clock distribution buffers
• Bus-oriented transmissions
• I/O port expansion

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SSOP-16 (SOT338-1) package variant. Confirm RoHS compliance status and check for any product discontinuation notices or end-of-life declarations from Nexperia before finalizing procurement plans.

Selection Notes

Select this component when an inverting function with high noise immunity and low power dissipation is required. Ensure the application utilizes a 5 V logic environment compatible with HCT specifications. Verify that the SSOP package dimensions fit the target PCB layout constraints.

Part Context

This part is a member of the 74HCT series, designed for compatibility with standard TTL logic families while offering CMOS performance benefits. It serves as a fundamental building block for signal buffering and level shifting in general-purpose digital electronics and embedded systems.

Replacement Considerations

Check for availability of the 74HCT366D (SO16) or 74HCT366PW (TSSOP16) variants if package changes are permissible. Verify pinout compatibility and electrical characteristics against alternative hex inverters from other manufacturers.
