74HC368DB,118

Overview

The Nexperia 74HC368DB,118 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 2.0 V to 6.0 V and utilizes a 16-lead SSOP package (SOT403-1). The device provides high noise immunity and low power dissipation, with input levels compatible with CMOS standards. It includes clamp diodes on all inputs to facilitate interfacing with voltages exceeding VCC using current-limiting resistors.

Feature Summary

• Hex inverting buffer/line driver with three-state outputs
• Active-low output enable control for high impedance OFF-state
• Wide supply voltage operation from 2.0 V to 6.0 V
• Input clamp diodes allow interface to voltages exceeding VCC

Applications

• Bus-oriented communications systems
• Clock buffering and distribution
• Memory address decoding

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SSOP-16 (SOT403-1) package variant when sourcing. Confirm that the component meets the required temperature range specifications (-40 °C to +125 °C) for the intended operational environment. Ensure design compatibility with the specified logic family characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring hex inverting buffers with tri-state capability. It is suitable for designs needing CMOS-level input compatibility and wide voltage tolerance. Consider the SSOP-16 package constraints regarding thermal dissipation and board space. Verify that the propagation delay and transition times meet the system's timing requirements at the operating voltage.

Part Context

This part belongs to the 74HC/HCT series of logic integrated circuits manufactured by Nexperia. It functions as a standard hex buffer/driver within the broader family of complementary metal-oxide-semiconductor logic devices. The DB suffix indicates the plastic small outline package type, specifically the SSOP variant, distinguishing it from other package options like SOIC or TSSOP.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify that any substitute maintains the same three-state functionality and inverting logic polarity. Ensure the replacement supports the required supply voltage range and package dimensions.
