74HC2G02DC-Q100H

Overview

The Nexperia 74HC2G02DC-Q100H is a dual 2-input NOR gate from the 74HC-Q100 series, housed in an 8-lead VSSOP (SOT765-1) package. 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 inputs with clamp diodes for interfacing voltages exceeding VCC. It complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Qualified to AEC-Q100 Grade 1 standards for automotive applications.
• Features reduced input threshold levels allowing direct interfacing to TTL logic levels.
• Includes internal clamp diodes on inputs to facilitate current limiting resistor usage.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Applications

• Automotive electronic systems requiring Grade 1 qualification.
• Logic level translation between CMOS and TTL interfaces.
• General-purpose digital signal processing in harsh environments.

Procurement Notes

Verify the specific suffix 'Q100H' matches the required automotive grade and tape-and-reel packaging configuration. Confirm that the VSSOP-8 package variant aligns with your PCB footprint requirements. Ensure design compliance with the specified operating temperature range and absolute maximum ratings to prevent device stress or failure during operation.

Selection Notes

Select this component when automotive reliability under AEC-Q100 Grade 1 is mandatory. Choose this part over non-qualified variants if the application demands extended temperature ranges up to +125 °C. Consider the HCT input thresholds if interfacing directly with legacy TTL logic sources without additional level shifting circuitry.

Part Context

This device belongs to the 74HC-Q100 family of automotive-grade logic ICs manufactured by Nexperia. It provides a compact solution for implementing NOR logic functions in space-constrained designs. The Q100 designation indicates adherence to strict automotive quality and reliability standards, distinguishing it from standard commercial logic counterparts.

Replacement Considerations

The 74HCT2G02DC-Q100H serves as a functional replacement for the HC variant where TTL-compatible input thresholds are required. Both share identical pinouts and physical dimensions but differ in input voltage specifications.

FAQ

What is the function of the input clamp diodes?

The input clamp diodes allow the use of current-limiting resistors to interface inputs to voltages that exceed the supply voltage (VCC).

Does this device support TTL logic levels?

Yes, the 74HC2G02-Q100 features reduced input threshold levels specifically designed to allow interfacing to TTL logic levels.
