74LVC1G125GS,132

Overview

The Nexperia 74LVC1G125GS,132 is a single bus buffer and line driver featuring a three-state output, housed in an XSON6 package (SOT1202). 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 inputs for noise immunity and IOFF circuitry to prevent backflow current during partial power-down states. Recommended operating conditions specify an ambient temperature range from -40 °C to +125 °C.

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 between mixed 3.3 V and 5 V logic environments

Applications

• Translating signals between mixed 3.3 V and 5 V digital systems
• Driving high-capacitance or transmission-line loads on data buses
• Isolating components during partial power-down sequences

FAQ

How does the IOFF feature function?

The IOFF circuitry automatically disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

What is the purpose of the Schmitt-trigger inputs?

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times, providing high noise immunity.
