74HC27BQ-Q100X

Overview

The Nexperia 74HC27BQ-Q100X is a triple 3-input NOR gate from the 74HC series, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Inputs include clamp diodes for interfacing with voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). It is housed in a DHVQFN14 package (SOT762-1) with side-wettable flanks.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range specified from -40 °C to +125 °C
• DHVQFN14 package with side-wettable flanks enabling automatic optical inspection

Applications

• Automotive electronic systems requiring robust logic gates
• Engine control units and body control modules
• Industrial applications demanding high noise immunity

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the intended environmental specifications for your application. Ensure compatibility with existing design constraints regarding supply voltage and input levels. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a triple 3-input NOR function is required in an automotive environment. The HC logic family offers CMOS low power dissipation suitable for battery-operated systems. The DHVQFN package provides a compact footprint with thermal enhancement. Verify that the input voltage levels align with the system's logic thresholds.

Part Context

This part belongs to the 74HC27-Q100 family of triple 3-input NOR gates designed for automotive applications. It shares functional similarities with other 74HC series logic devices but is specifically qualified for harsh environments. The BQ suffix denotes the DHVQFN14 package type, distinguishing it from SO or TSSOP variants within the same logical family.

Replacement Considerations

Direct replacements must maintain AEC-Q100 Grade 1 qualification and identical logic functionality. Verify pinout compatibility if substituting with packages from different manufacturers. Ensure the alternative device supports the required supply voltage range and temperature specifications.
