74HCT27PW-Q100J

Overview

The Nexperia 74HCT27PW-Q100J is a triple 3-input NOR gate manufactured using Si-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device is housed in a TSSOP14 (SOT402-1) package with 14 leads. It has been qualified to the AEC-Q100 Grade 1 standard for automotive applications, supporting an ambient temperature range from -40 °C to +125 °C. Static characteristics include low power dissipation and high noise immunity.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL input switching levels for direct interfacing with TTL logic systems
• Wide operating temperature range suitable for harsh environments
• High noise immunity and robust latch-up performance

Applications

• Automotive electronic control units
• Industrial logic processing circuits
• Consumer electronics requiring TTL compatibility

Procurement Notes

Verify that the ordering suffix matches the specific package variant required for your design. Confirm the revision level of the datasheet aligns with your manufacturing specifications. Ensure the component meets the AEC-Q100 Grade 1 requirements if deployed in automotive contexts. Cross-reference pin assignments with your schematic to prevent integration errors during assembly.

Selection Notes

Select this component when TTL-compatible inputs are necessary alongside NOR logic functionality. The wide supply voltage tolerance allows flexibility in power distribution networks. Consider the TSSOP14 package dimensions for PCB layout constraints. Evaluate thermal derating requirements based on the maximum power dissipation limits specified for the plastic thin shrink small outline package.

Part Context

This part belongs to the 74HCT27-Q100 family of triple 3-input NOR gates. It shares functional similarities with other members of the series but differs in package type and specific electrical parameters defined by the HCT logic level. The PW suffix indicates the TSSOP14 package configuration, distinguishing it from SO or DHVQFN variants within the same logical family.

Replacement Considerations

Direct substitutes include the 74HC27PW-Q100J, though it utilizes CMOS input levels rather than TTL. Other package variants such as 74HCT27D-Q100J (SO14) or 74HCT27BQ-Q100J (DHVQFN14) offer identical logic functions with different physical footprints.
