74HCT2G34GW,125

Overview

The Nexperia 74HCT2G34GW,125 is a dual buffer gate belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features push-pull outputs with non-inverting polarity. The device contains two independent channels housed in a 6-lead TSSOP plastic thin shrink small outline package (SOT363-2). Inputs include clamp diodes for interfacing with voltages exceeding VCC using current limiting resistors. Static characteristics specify high-level output voltage of 4.18 V minimum at -4.0 mA load and low-level output voltage of 0.26 V maximum at 4.0 mA load. Dynamic performance includes a propagation delay of 18 ns typical at 4.5 V with 50 pF load.

Feature Summary

• Provides balanced propagation delays for signal buffering applications
• Features input clamp diodes allowing interface to voltages above VCC
• Ensures latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Signal buffering in digital circuits
• Line driving applications requiring TTL level inputs
• Interface circuits utilizing current limiting resistors

Procurement Notes

Verify the specific ordering suffix ',125' corresponds to the standard tape and reel packaging configuration as defined by Nexperia. Confirm that the component meets RoHS compliance requirements for the intended market. Ensure the design accounts for the specified operating temperature range of -40 °C to +125 °C during thermal analysis.

Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS output drive capabilities. The HCT series ensures compatibility with standard TTL logic families while offering lower power dissipation. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system power architecture before integration into the design.

Part Context

This part belongs to the Nexperia 74HCT2G34 dual buffer gate series. It shares functional similarities with the 74HC2G34 but utilizes HCT logic technology to accept TTL input levels. The device is designed for surface-mount assembly in compact electronic systems requiring dual-channel buffering functionality.

Replacement Considerations

Direct substitutes include the 74HC2G34GW,125 for HC logic variants or the 74LVC2G34GW,125 for LVC logic variants. Cross-family replacements require verification of input voltage thresholds and supply voltage compatibility.
