74LVC3G17DC,125

Overview

The Nexperia 74LVC3G17DC,125 is a triple non-inverting Schmitt trigger buffer housed in an 8-lead VSSOP package (SOT765-1). 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 features CMOS low-power consumption with a maximum supply current of 4 μA and IOFF circuitry for partial power-down applications. Propagation delay ranges from 1.0 ns to 8.5 ns depending on the supply voltage.

Feature Summary

• Triple non-inverting buffers with Schmitt-trigger inputs for high noise immunity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Direct interface capability with TTL levels and mixed 3.3 V/5 V environments

Applications

• Wave and pulse shapers for highly noisy environments

Procurement Notes

Verify the specific ordering suffix ',125' corresponds to the required tape-and-reel packaging configuration. Confirm that the VSSOP8 (SOT765-1) package dimensions align with the target PCB footprint. Ensure the component meets RoHS3 compliance requirements for the intended manufacturing process.

Selection Notes

Select this component when three independent non-inverting buffers with hysteresis are required in a compact surface-mount form factor. The wide supply voltage range allows compatibility with various logic families. The inclusion of Schmitt triggers makes it suitable for signal conditioning where input waveforms may have slow rise or fall times.

Part Context

This part belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. The 'DC' suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package variant. It shares functional characteristics with other members of the 74LVC3G17 series but differs in physical housing and pinout geometry compared to TSSOP or XSON packages.
