74LVC2G125GM,125

Overview

The Nexperia 74LVC2G125GM,125 is a dual bus buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down applications. It provides an output drive capability of ±24 mA at VCC = 3.0 V and complies with JEDEC standards for various voltage ranges.

Feature Summary

• Features IOFF circuitry that disables the output to prevent potentially damaging backflow currents when the device is powered down.
• Incorporates Schmitt-trigger action at all inputs to ensure tolerance of slower input rise and fall times.
• Supports direct interface with TTL levels and allows use as translators in mixed 3.3 V and 5 V environments.

Applications

• Partial power-down mode operation
• Mixed 3.3 V and 5 V translation environments
• Bus buffering and line driving

Procurement Notes

Verify the specific package type against the ordering information table, as the GM suffix corresponds to the XQFN8 package which was removed from the standard product data sheet in revision 17. Confirm current production status directly with Nexperia or authorized distributors, as this specific variant may be obsolete or superseded by other packages like DC or DP.

Selection Notes

Select this component for applications requiring dual-channel buffering with high noise immunity and low power consumption. Ensure the design accommodates the specified operating temperature range and utilizes the IOFF functionality if partial power-down requirements exist. Verify compatibility with system voltage levels given the wide supply range.

Part Context

This part belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. The 74LVC2G125 series specifically provides dual buffers with three-state outputs. While the GM package version appears in older distributor records, the official datasheet lists alternative packages such as TSSOP8, VSSOP8, and XSON8 variants.

Replacement Considerations

The 74LVC2G125GF and 74LVC2G125GD are listed as removed types in the revision history. Consider using the 74LVC2G125DC (VSSOP8) or 74LVC2G125DP (TSSOP8) as functional equivalents available in the current product specification.
