74HC27D-Q100J

Overview

The Nexperia 74HC27D-Q100J is a triple 3-input NOR gate integrated circuit within the 74HC series. It operates on a supply voltage range of 2.0 V to 6.0 V and is qualified to AEC-Q100 Grade 1 standards for automotive applications. The device features CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. It includes input clamp diodes to interface with voltages exceeding VCC using current limiting resistors. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is housed in an SOIC-14 package (SOT108-1) and functions across ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Triple 3-input NOR logic functionality with CMOS architecture
• Wide operating temperature range spanning -40 °C to +125 °C
• Input clamp diodes enabling direct interfacing with voltages above VCC

Applications

• Automotive electronic systems requiring robust logic gating

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 74HC27-Q100 family includes multiple options such as TSSOP and DHVQFN. Confirm the exact temperature grade and compliance documentation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when a triple 3-input NOR function is required in automotive or industrial settings. Ensure the design accommodates the specified supply voltage range and utilizes appropriate current limiting for inputs exceeding VCC due to the presence of internal clamp diodes.

Part Context

This part belongs to the Nexperia 74HC27-Q100 family of triple 3-input NOR gates. It shares functional characteristics with other variants like the 74HC27PW-Q100J and 74HC27BQ-Q100J, differing primarily in physical packaging dimensions and terminal configurations while maintaining identical electrical performance profiles.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC27 equivalents meeting AEC-Q100 Grade 1 standards. Verify pinout compatibility and logic level thresholds when replacing with non-Nexperia parts.
