Overview
The Nexperia 74HCT27D-Q100J is a triple 3-input NOR gate within the 74HCT logic family, designed for automotive applications. It operates on 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 features TTL input levels and includes clamp diodes on inputs. It is housed in a SOIC-14 (SOT108-1) package with 14 leads. Propagation delay is specified at a maximum of 26 ns at 4.5 V. Static characteristics include low power dissipation and high noise immunity.
Feature Summary
- Qualified to AEC-Q100 Grade 1 standards for automotive use
- Features CMOS low power dissipation and high noise immunity
- Inputs equipped with clamp diodes for overvoltage interfacing
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Applications
- Automotive electronic systems requiring NOR logic functions
- Industrial control circuits operating in wide temperature ranges
- Mixed voltage interface applications utilizing TTL-compatible inputs
Procurement Notes
Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application environment. Ensure design parameters align with the recommended operating conditions provided in the official datasheet to maintain reliability.
Selection Notes
Select this component when a triple 3-input NOR function is required in automotive or industrial environments. The HCT series ensures compatibility with TTL logic levels while maintaining CMOS performance benefits. Consider the SOIC-14 package dimensions for PCB layout constraints and verify thermal dissipation capabilities against the total power dissipation limits defined in the specifications.
Part Context
This part belongs to the Nexperia 74HCT27-Q100 series, which includes variants in different packages such as TSSOP14 and DHVQFN14. All variants share the same logical functionality and electrical characteristics but differ in physical footprint and mounting style. The D suffix specifically denotes the SOIC plastic small outline package configuration.
Replacement Considerations
Direct replacements must match the 74HCT27 logic type, SOIC-14 package, and AEC-Q100 qualification. Verify pinout compatibility and electrical parameters before substitution.
