74HC2G34GV-Q100H

Overview

The Nexperia 74HC2G34GV-Q100H is a dual buffer gate qualified to AEC-Q100 Grade 1 standards for automotive applications. 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 balanced propagation delays. Inputs include clamp diodes to allow interfacing with voltages exceeding VCC using current limiting resistors. It complies with JEDEC JESD8C and JESD7A standards and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1.
• Wide supply voltage range supporting 2.0 V to 6.0 V operation.
• High noise immunity and CMOS low power dissipation characteristics.
• Input clamp diodes enable interface to voltages exceeding VCC.

Applications

• Automotive electronic systems requiring robust logic buffering.
• Signal conditioning in environments with high noise immunity requirements.
• Voltage level translation interfaces utilizing current limiting resistors.

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the intended temperature range specifications for the target application environment. Ensure design compliance with absolute maximum ratings to prevent permanent damage. Cross-reference marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when automotive reliability per AEC-Q100 Grade 1 is mandatory. Choose this part for designs requiring dual buffering within a compact SC-74 package. Consider the wide supply voltage flexibility for mixed-voltage system architectures. Evaluate the input clamp diode capability if interfacing with external voltage sources beyond the supply rail.

Part Context

This component belongs to the Nexperia 74HC2G34-Q100 family of dual buffer gates. It shares functional similarities with other members of the series but is distinguished by its specific SC-74 (SOT457) surface-mounted package configuration. The GV suffix indicates the plastic surface-mounted package type, differentiating it from TSSOP variants.

Replacement Considerations

Direct substitutes include the 74HC2G34GW-Q100H, which utilizes a TSSOP6 package instead of SC-74. Verify pinout compatibility and physical footprint constraints before substituting packages within the same logical family.
