74LVC2G125GF,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVC2G125GF,115 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 an output drive current of ±24 mA at VCC = 3.0 V. The device incorporates Schmitt-trigger inputs for noise immunity and IOFF circuitry to prevent backflow currents during partial power-down states. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across specified voltage ranges.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides high noise immunity through Schmitt-trigger action on all inputs.
• Enables partial power-down mode operation via integrated IOFF circuitry.
• Supports direct interfacing with TTL logic levels in mixed voltage environments.

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between mixed 3.3 V and 5 V logic systems.
• Driving high-capacitance or transmission-line loads as a line driver.
• Managing data buses requiring isolated three-state control.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific GF suffix against the official datasheet revision history, noting that type number 74LVC2G125GF was removed from the product specification in version 19 released in August 2024. Confirm package availability and lead times directly with Nexperia or authorized distributors, as this variant may no longer be in production.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require bidirectional level shifting between 1.65 V and 5.5 V domains. Ensure the application utilizes the IOFF feature if the system involves hot-swap scenarios or partial power-down sequences to protect downstream components from reverse current flow.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74LVC family of low-voltage CMOS logic devices. The 74LVC2G125 specifically functions as a dual buffer/line driver. While the standard 74LVC2G125 is available in packages such as TSSOP8, VSSOP8, and XSON8, the GF suffix indicates a specific package configuration that has been discontinued in recent revisions.
