74HC2G34GW-Q100H

Overview

The Nexperia 74HC2G34GW-Q100H is a dual buffer gate qualified to AEC-Q100 Grade 1 for automotive applications. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and balanced propagation delays with unlimited input rise and fall times. Inputs include clamp diodes to interface with voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A, offering ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Inputs include clamp diodes for interfacing to voltages in excess of VCC

Applications

• Automotive electronic systems
• Signal buffering and level translation
• General-purpose logic circuits requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC2G34 series includes variants like GW (TSSOP6) and GV (SC-74). Confirm that the HC logic family aligns with your system's voltage requirements, distinct from the HCT variant which uses TTL input levels. Ensure design compliance with the specified operating temperature range and absolute maximum ratings to prevent device damage.

Selection Notes

Select this component when a dual non-inverting buffer is required for automotive-grade designs. The HC logic family is suitable for systems operating between 2.0 V and 6.0 V. Consider the TSSOP6 or SC-74 packages based on board space constraints. Verify that the CMOS input levels are compatible with the driving source, distinguishing it from the HCT version if TTL-level inputs are necessary.

Part Context

This part belongs to the Nexperia 74HC(HCT)2G34-Q100 family of dual buffer gates. These devices are designed for automotive applications, meeting rigorous reliability standards. The family offers flexibility through different package options and logic families (HC vs. HCT), allowing designers to optimize for voltage compatibility and power consumption while maintaining small form factors.

Replacement Considerations

Direct substitutes within the same family include the 74HCT2G34GW-Q100H, which shares the same package but utilizes TTL-compatible input levels instead of CMOS levels. Designers must verify input voltage thresholds when swapping between HC and HCT variants to ensure proper signal interpretation.
