74HCT4075DB,118

Overview

The Nexperia 74HCT4075DB,118 is a triple 3-input OR gate in the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device is housed in an SO14 (SOT108-1) package with 14 leads. Static characteristics include a maximum LOW-level output voltage of 0.4 V at 4.0 mA load and HIGH-level output voltage of 3.7 V at -4.0 mA load. Dynamic performance specifies a propagation delay of up to 36 ns at 4.5 V and 36 ns at 5.5 V under standard test conditions.

Feature Summary

• Complies with JEDEC standard no. 7A for robust operation
• Features ESD protection exceeding 2000 V via Human Body Model
• Includes clamp diodes on inputs for overvoltage interfacing

Applications

• Digital logic circuit design requiring triple OR functionality
• Signal processing systems utilizing TTL-compatible interfaces
• Industrial control applications operating within specified temperature ranges

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package variant. Ensure compliance with RoHS directives and check for any recent product change notices that may affect specifications or availability status prior to finalizing procurement orders.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS noise immunity. The HCT series ensures direct interface with standard TTL logic families without additional level shifting. Consider the SO14 package dimensions for PCB layout constraints and verify thermal dissipation requirements against the total power dissipation limits defined in the datasheet.

Part Context

This part belongs to the 74HCT4075 series of triple 3-input OR gates manufactured by Nexperia. It shares functional similarities with other members of the 74HC/HCT logic family but is distinguished by its specific TTL input threshold voltages. The DB suffix indicates the SO14 plastic small outline package configuration suitable for surface mount assembly.

Replacement Considerations

Direct substitutes include the 74HC4075D for CMOS-level input variants. Cross-family replacements require verification of input voltage thresholds to ensure compatibility with existing TTL drivers.
