74LVC2G126GM,125

Overview

The Nexperia 74LVC2G126GM,125 is a dual bus buffer and line driver featuring three-state outputs controlled by active-high 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 IOFF circuitry for partial power-down applications. It provides ±24 mA output drive at VCC = 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, and JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Dual buffer/line driver with three-state outputs controlled by nOE inputs
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slower rise and fall times
• Overvoltage tolerant inputs allow direct interface with TTL levels

Applications

• Mixed 3.3 V and 5 V environments
• Partial power down applications
• Bus buffering and line driving

Procurement Notes

Verify the specific package designation against official documentation, as the GM suffix corresponds to an XQFN8 package which was removed from the standard product data sheet in revision 15. Confirm current manufacturing status and availability through authorized Nexperia channels or distributors, as this specific variant may be obsolete or superseded by other package options like DP, DC, or GT.

Selection Notes

Select this component when designing systems requiring dual-channel buffering with three-state control in mixed-voltage environments. Ensure the application utilizes the IOFF feature if partial power-down capabilities are required. Verify that the input signal characteristics align with the Schmitt-trigger thresholds and that the operating temperature range meets the system's environmental requirements.

Part Context

The 74LVC2G126 belongs to the Nexperia 74LVC logic family, designed for low-voltage CMOS applications. While the datasheet lists multiple package types such as TSSOP8, VSSOP8, and various XSON8 variants, the GM suffix specifically denotes an XQFN8 package. Note that revision history indicates the removal of the 74LVC2G126GM type number in later revisions, suggesting potential discontinuation or replacement.

Replacement Considerations

Consult the official Nexperia website for the most recent product status regarding the 74LVC2G126GM. Other available packages for the 74LVC2G126 function include 74LVC2G126DP (TSSOP8), 74LVC2G126DC (VSSOP8), and 74LVC2G126GT (XSON8).
