74LVC1G125GV,125

Overview

The Nexperia 74LVC1G125GV,125 is a single bus buffer and line driver featuring a 3-state output. It operates within a supply voltage range of 1.65 V to 5.5 V and accepts 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 states. It provides an output drive capability of ±24 mA at VCC = 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.

Feature Summary

• Provides non-inverting buffering with high-noise-immunity Schmitt-trigger inputs
• Enables safe partial power-down operation via integrated IOFF circuitry
• Supports direct interfacing with TTL logic levels across wide voltage ranges

Applications

• Translating signals between mixed 3.3 V and 5 V digital environments
• Driving high-capacitance or transmission-line loads on data buses
• Isolating components in partially powered-down system architectures

Procurement Notes

Verify the specific suffix GV corresponds to the SC-74A (SOT753) package configuration required for your PCB layout. Confirm that the operating temperature range of -40 °C to +125 °C aligns with your environmental specifications. Ensure input transition rates remain within the recommended limits defined in the datasheet to maintain signal integrity.

Selection Notes

Select this component when a single-channel, non-inverting buffer with controlled 3-state output is required. The wide supply voltage compatibility allows it to interface directly with both 3.3 V and 5 V logic families without external level shifters. The inclusion of IOFF functionality makes it suitable for systems requiring safe hot-swapping or partial power management.

Part Context

This part belongs to the Nexperia 74LVC family of low-voltage CMOS logic devices. The LVC series is designed for applications requiring low power consumption and high speed while maintaining compatibility with standard logic voltage levels. The 74LVC1G125 specifically addresses the need for buffered outputs with tri-state control in compact surface-mount packages.

Replacement Considerations

Direct functional equivalents include other single-buffer 3-state drivers from the same family, such as the 74LVC1G125GW (TSSOP5) or 74LVC1G125GM (XSON6). Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit.
