The SN74LVC1G17DCKR from TI is a single Schmitt-trigger buffer with 1.65-5.5V supply and hysteresis for signal conditioning in tiny SC-70-5 package.
The SN74LVC1G17DCKR is a single Schmitt-trigger buffer from Texas Instruments in SC-70-5, operating from 1.65V to 5.5V. Unlike the SN74AHC1G14 (inverting Schmitt-trigger), this device is non-inverting: the output follows the input logic level, but with Schmitt-trigger hysteresis on the input. The positive-going threshold (VT+) is typically 1.9V at 3.3V supply, and the negative-going threshold (VT-) is typically 0.9V, providing 1.0V of hysteresis. This hysteresis provides noise immunity and clean output transitions for slowly-changing or noisy input signals. Key applications include: (1) Signal conditioning – converting slowly-varying sensor outputs (thermistors, photodiodes) to clean digital levels; (2) Level translation – the wide input threshold range accommodates signals from different voltage domains (1.8V input to 3.3V output); (3) Clock conditioning – cleaning up noisy or slow-edge clock signals before they reach counters or flip-flops; (4) Switch debounce – the hysteresis filters out contact bounce from mechanical switches. The LVC family provides propagation delay of 3.5ns at 5V and 5.5ns at 3.3V. The output can source/sink 24mA at 3.3V. The quiescent supply current is 1uA maximum. The SC-70-5 package (2.0 x 1.25mm) is approximately half the size of SOT-23-5, saving PCB area in compact designs.
