74HCT367D,653

Overview

The Nexperia 74HCT367D,653 is a hex 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 supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a 16-lead plastic small outline package (SO16) with a body width of 3.9 mm. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Hex buffer/line driver architecture with six independent channels
• Three-state outputs allowing high impedance OFF-states when disabled
• TTL-compatible input levels for direct logic interfacing
• Input clamp diodes enabling safe operation with voltages above VCC

Applications

• Bus-oriented transmissions
• Clock buffering and distribution
• Memory and signal driving applications

Procurement Notes

Verify the specific suffix '653' corresponds to the SO16 (SOT109-1) package variant. Confirm that the HCT logic family matches the system's 5V TTL input requirements rather than HC CMOS standards. Ensure environmental specifications align with the required operating temperature range of -40 °C to +125 °C before finalizing procurement.

Selection Notes

Select this component when a hex buffer with tri-state capability is required for bus isolation or signal driving in 5V logic systems. The HCT series ensures compatibility with standard TTL inputs. Verify that the 16-pin SO package fits the PCB layout constraints and that the thermal dissipation characteristics meet the application's power requirements under maximum load conditions.

Part Context

This part belongs to the Nexperia 74HCT367 product line, which is part of the broader 74HC/HCT logic family. It serves as a hex buffer/line driver designed for high-speed digital applications requiring bus holding or data movement. The device is manufactured using CMOS technology to ensure low power dissipation while maintaining high noise immunity.

Replacement Considerations

Cross-reference with other manufacturers offering the 74HCT367 specification. Ensure pinout compatibility and verify that electrical parameters such as propagation delay and output drive current meet or exceed the original design requirements.
