74HCT2G34GV-Q100H

Overview

The Nexperia 74HCT2G34GV-Q100H is a dual buffer gate from the 74HCT logic family, housed in a SC-74 (TSOP6) package with six leads. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-level input compatibility, balanced propagation delays, and high noise immunity. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC and meets AEC-Q100 Grade 1 automotive qualification standards.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• TTL level input compatibility
• High noise immunity and CMOS low power dissipation

Applications

• Automotive applications
• Signal buffering
• Level translation between TTL and CMOS domains

Procurement Notes

Verify the specific ordering suffix 'GV' corresponds to the SC-74 package variant when sourcing. Confirm that the '-Q100H' designation aligns with required automotive grade specifications. Ensure environmental operating conditions match the specified -40 °C to +125 °C range for the target application environment.

Selection Notes

Select this component when a dual non-inverting buffer with TTL-compatible inputs is required in a compact surface-mount package. It is suitable for designs needing high noise immunity and automotive reliability. Consider the 74HC2G34 variant if CMOS-level inputs are preferred instead of TTL levels.

Part Context

This part belongs to the Nexperia 74HCT2G34-Q100 series of dual buffer gates. It shares functional characteristics with other members of the 74HCT family but is distinguished by its specific SC-74 packaging and automotive-grade qualification. The device provides two independent buffer channels in a minimal footprint.

Replacement Considerations

The 74HCT2G34GW-Q100H serves as a direct functional substitute, differing only in package type (TSSOP6 instead of SC-74). Verify pinout compatibility and physical dimensions before substituting.
