74HCT368D,653

Overview

The Nexperia 74HCT368D,653 is a hex inverting buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device provides six independent data paths with high noise immunity and low power consumption. It is housed in an SO16 plastic small outline package (SOT109-1) suitable for surface mount applications.

Feature Summary

• Hex inverting buffer/line driver with three-state outputs
• TTL-compatible input levels for direct interface with logic systems
• Active-low output enable control for bus management
• High noise immunity and CMOS low power dissipation

Applications

• Bus-oriented transmissions
• Clock buffering and distribution
• Memory address decoding
• Drive for CMOS, NMOS, or TTL devices

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status and environmental declarations against current regulatory requirements. Ensure the component temperature range aligns with the intended operational environment before finalizing procurement orders.

Selection Notes

Select this component when interfacing TTL logic sources with CMOS loads requiring signal inversion and bus isolation. The HCT series ensures compatibility with standard 5 V logic families. Verify that the SO16 package dimensions fit the target PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices manufactured by Nexperia. It serves as a standard hex buffer solution for digital circuit designs requiring signal conditioning and isolation. The device complements other 74-series logic components for complex system integration.

Replacement Considerations

Check for pin-compatible alternatives from other manufacturers if supply constraints exist. Ensure any substitute maintains identical logic functionality, voltage ranges, and package specifications.
