74HC2G125GD,125

Overview

The Nexperia 74HC2G125GD,125 is a dual buffer/line driver with 3-state outputs controlled by active LOW enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and supports CMOS input levels. The device features clamp diodes on inputs for interfacing with voltages exceeding VCC using current limiting resistors. It includes two buffers with independent output enables. The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Dual buffer configuration with independent 3-state outputs controlled by active LOW enable inputs
• Wide supply voltage operation ranging from 2.0 V to 6.0 V
• Input clamp diodes allow interfacing to voltages in excess of VCC when used with current limiting resistors
• High noise immunity and low power dissipation characteristics typical of CMOS technology

Applications

• Line driving applications requiring signal buffering
• Mixed voltage environments utilizing overvoltage tolerant inputs
• General purpose digital logic buffering

Procurement Notes

Verify the specific package type against the ordering suffix. The GD suffix corresponds to the XSON8 package, which was removed from this data sheet version. Confirm availability of the GD variant or select an alternative package such as DP (TSSOP8) or DC (VSSOP8) listed in the official ordering information table.

Selection Notes

Select this component for applications requiring dual buffered signals with high-impedance control. Ensure the design accommodates the 2.0 V to 6.0 V supply range. Verify that the required input voltage levels are compatible with CMOS standards. Check thermal derating requirements if operating near the maximum temperature limit.

Part Context
