74HC2G34GV,125

Overview

The Nexperia 74HC2G34GV,125 is a dual buffer gate from the 74HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device features CMOS input levels, balanced propagation delays, and unlimited input rise/fall times. It utilizes the SC-74 (TSOP6) package with six leads. Static characteristics include high noise immunity and low power dissipation. Dynamic performance at 4.5 V with 50 pF load capacitance shows a typical propagation delay of 9 ns and transition time of 6 ns.

Feature Summary

• Dual non-inverting buffer configuration
• Wide operating voltage range from 2.0 V to 6.0 V
• High noise immunity with balanced propagation delays
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Signal buffering in digital circuits
• Line driving applications
• Interface between different logic families

Procurement Notes

Verify the ordering suffix '125' corresponds to the standard tape and reel packaging format specified by Nexperia for this component series. Confirm that the SC-74 package variant matches the design footprint requirements. Ensure compliance with RoHS directives and REACH regulations as stated in the product data sheet before finalizing procurement specifications.

Selection Notes

Select the 74HC2G34GV when a dual buffer with wide voltage compatibility is required. This model is suitable for systems operating between 2.0 V and 6.0 V. Choose the GV suffix specifically for the SC-74 surface-mount package. Verify that the CMOS input levels align with the source logic family voltages in the target application design.

Part Context

This component belongs to the Nexperia 74HC/HCT2G34 series of dual buffer gates. It is part of the broader 74HC logic family designed for general-purpose digital applications. The GV designation identifies the specific SC-74 plastic surface-mounted package variant, distinguishing it from other package options like TSSOP6 available within the same logical function family.

Replacement Considerations

Direct substitutes include the 74HC2G34GW,125 which shares identical electrical characteristics but utilizes the TSSOP6 package. Cross-reference pinouts and package dimensions carefully when replacing components to ensure mechanical compatibility.
