74HCT368PW,118

Overview

The Nexperia 74HCT368PW,118 is a hex inverting buffer and line driver featuring three-state outputs. It belongs to the HCT logic series, designed for TTL-compatible input levels while utilizing CMOS technology for low power dissipation. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides six independent inverting buffers with output enable controls (nOE) that allow high-impedance states. The component is housed in a TSSOP16 plastic thin shrink small outline package (SOT403-1), suitable for surface mount applications across an extended temperature range.

Feature Summary

• Hex inverting buffer configuration with dedicated output enable inputs controlling three-state functionality
• TTL-compatible input levels ensuring direct interface with standard logic families
• CMOS construction providing low power consumption and high noise immunity
• Integrated input clamp diodes facilitating safe interfacing with voltages exceeding the supply rail

Applications

• Bus-oriented transmission systems requiring signal inversion and isolation
• Clock drivers where controlled three-state output buffering is necessary
• Memory address decoding circuits utilizing inverting buffer stages
• I/O port expansion designs involving parallel data transfer lines

Procurement Notes

Verify the specific ordering code suffix matches the required packaging format. Confirm the revision level aligns with current design specifications. Ensure the TSSOP16 footprint dimensions correspond to the target PCB layout constraints. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS efficiency. The three-state capability allows multiple drivers to share a common bus without contention. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range. Consider the thermal derating requirements if operating near the upper temperature limits in enclosed environments.

Part Context

This part is part of the broader 74HCT family of logic integrated circuits manufactured by Nexperia. It shares functional similarities with other hex buffers but is distinct due to its inverting nature and three-state control. The PW suffix indicates the TSSOP16 package variant, differentiating it from SO16 or other package options available within the same logical family.

Replacement Considerations

Direct substitutes include the 74HC368PW,118, though input voltage thresholds differ significantly between HC and HCT series. Other manufacturers may offer equivalent hex inverting three-state buffers, but pin compatibility and electrical parameters must be validated against the original datasheet specifications.
