74HCT365DB,118

Overview

The Nexperia 74HCT365DB,118 is a hex buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (OE1 and OE2). It belongs to the HCT logic family, utilizing TTL-compatible input levels. The device 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. It is housed in a 16-lead SSOP plastic package (SOT338-1) with a body width of 5.3 mm.

Feature Summary

• Hex buffer/line driver architecture with non-inverting outputs
• Three-state output capability controlled by dedicated enable pins
• TTL-compatible input voltage levels for direct interfacing
• CMOS low power dissipation characteristics

Applications

• Memory address buffering
• Clock distribution circuits
• Carry propagation in arithmetic logic units

Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm that the specific ordering suffix matches the required SSOP package variant. Ensure compliance with RoHS directives and check for any product change notices affecting manufacturing origin or material composition prior to final procurement decisions.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance benefits. The HCT series ensures reliable interfacing with standard TTL logic families while maintaining low static power consumption. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure correct logic threshold behavior and signal integrity.

Part Context

This part is a member of the 74HCT365 family, which includes variants such as the 74HCT365D (SOIC package) and 74HCT365PW (TSSOP package). All variants share identical electrical specifications but differ in physical packaging dimensions. The DB suffix specifically denotes the SSOP form factor, distinguishing it from other surface-mount options available within the same logical function group.

Replacement Considerations

The 74HCT365PW,118 serves as a verified substitute offering identical electrical performance in a TSSOP-16 package. Cross-package replacements require verification of PCB footprint compatibility and thermal management requirements due to differing physical dimensions.
