SN74LVC1G17DBVR Single Schmitt-Trigger Buffer (C7836, SOT-23-5)

Clean up noisy logic lines and stabilize your digital signals with the SN74LVC1G17DBVR single-channel buffer. Unlike standard buffers, this IC features a Schmitt-trigger input with built-in hysteresis. This means it can take slow, noisy, or degraded input signals and convert them into sharp, crisp, and jitter-free digital outputs, making it incredibly valuable in environments with high electromagnetic interference (EMI), such as FPV drones and heavy-duty robotics.

Operating across a wide voltage range of 1.65V to 5.5V, it easily interfaces with both 3.3V microcontrollers (like STM32) and standard 5V logic systems. Furthermore, its inputs are overvoltage-tolerant, allowing you to safely feed 5V signals into the chip even when it is powered by a lower voltage. Packaged in a tiny SOT-23-5 format, it is the perfect space-saving solution for signal conditioning, switch debouncing, and robust logic isolation.

Key Features:

• Schmitt-Trigger Input: Provides hysteresis to filter out noise, ensuring clean and stable logic transitions from degraded signals.

• Wide Operating Range: Functions reliably on supply voltages from 1.65V up to 5.5V.

• Overvoltage Tolerant: Inputs safely accept up to 5.5V regardless of the supply voltage, making it great for level shifting.

• High Drive Strength: Capable of sinking or sourcing up to 32mA (at 5V), easily driving long traces or LEDs.
