74HCT366PW,112

Overview

The Nexperia 74HCT366PW,112 is a hex inverting buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (OE1, OE2). It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides TTL-compatible input levels and includes clamp diodes on all inputs for overvoltage interfacing. Packaged in a 16-lead TSSOP (SOT403-1), it supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Hex inverting buffer/line driver with three-state outputs
• TTL-compatible input levels for direct interface
• Active LOW output enable control via two separate pins
• Input clamp diodes allow interfacing to voltages exceeding VCC

Applications

• Bus-oriented transmissions
• Clock buffering and distribution
• Memory address decoding
• Line driving applications requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix '112' against current Nexperia documentation to confirm package type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements relevant to your manufacturing region. Ensure design-in validation accounts for the specified thermal derating characteristics for the TSSOP16 package at elevated operating temperatures.

Selection Notes

Select this component when TTL logic compatibility is required alongside CMOS low power dissipation. The HCT series ensures reliable switching with standard TTL voltage thresholds. Verify that the application requires inverting functionality and three-state bus isolation capabilities. Consider the TSSOP16 package dimensions if PCB space constraints are critical compared to standard SO packages.

Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other 74HCT hex buffers but specifically provides inverting logic and three-state control. The PW suffix denotes the plastic thin shrink small outline package variant, distinguishing it from standard SO or SSOP versions within the same logical family.

Replacement Considerations

Direct functional equivalents include the 74HC366PW,112, though input voltage thresholds differ (CMOS vs. TTL). Other manufacturers producing JEDEC-compliant 74HCT366 devices in TSSOP16 packages may serve as substitutes, provided pinout and electrical characteristics match the original specification.
