Product details

Single Schmitt-trigger inverter for signal conditioning on automotive and industrial rails

The SN74LVC1G14QDRYRQ1: The Schmitt-trigger input provides hysteresis for noise-immune switching on slow or noisy signals — think switch debounce, sensor conditioning, or clock shaping on a motor-drive or ECU board. Output drive is rated 32 mA source and sink, enough to drive a downstream logic input or a small LED indicator. Propagation delay is 6 ns typical at 5 V with a 50 pF load, fast enough for most digital signal paths.

6-SON package — footprint and layout considerations

The part comes in a 6-UFDFN package, also designated 6-SON with dimensions 1.45 mm x 1.0 mm. The leads are on the bottom, so the part is not hand-solderable without a hot-air station or reflow oven. Stencil aperture design and solder paste volume need attention to avoid bridging between the closely spaced pads. The package is surface-mount only, specified for Tape & Reel or Cut Tape delivery.

The 74LVC1G14 function is a standard TI catalog item with multiple package variants.

Frequently asked questions

What is the difference between SN74LVC1G14QDRYRQ1 and SN74LVC1G14DBVR?

Both are the same 74LVC1G14 single Schmitt-trigger inverter. The difference is the package: the QDRYRQ1 suffix is the 6-SON (1.45 mm x 1.0 mm) package qualified to AEC-Q100, while the DBVR suffix is the SOT-23-5 package. The QDRYRQ1 is the automotive-grade variant with the smaller footprint.

Does SN74LVC1G14QDRYRQ1 have a replacement or second source?

For dual-sourcing, evaluate functionally equivalent single Schmitt-trigger inverters from other manufacturers in the same package and temperature grade, but verify pin compatibility and electrical specs against your design.
