The 74LVC1G14W5-7 from Diodes Incorporated is a single Schmitt-trigger inverter in an ultra-small SC-70-5 (SOT-353) package. Operating from 1.65V to 5.5V with overvoltage tolerant inputs up to 5.5V, the device provides noise-immune signal inversion. The Schmitt-trigger input hysteresis ensures clean output transitions on slow or noisy input signals. Propagation delay is 5.5ns typical at 3.3V with +/-24mA output drive. The device is fully specified from -55C to +125C.

The 74LVC1G14W5-7 is a single-stage Schmitt-trigger inverter. (1) Schmitt-Trigger Input: The input stage has dual thresholds (VT+ and VT-) providing hysteresis. When the input rises past VT+, the output switches low. When the input falls below VT-, the output switches high. This hysteresis prevents output oscillation on slow or noisy edges. (2) Inverter: The output is the logical complement of the cleaned-up input. (3) Overvoltage Tolerance: Input protection allows voltages up to 5.5V regardless of VCC, enabling level translation from higher to lower voltage domains.
