SN74LVC3G17DCTR Triple Schmitt-Trigger Buffer (MSOP-8)

Clean up degraded signals and protect your logic circuits with the SN74LVC3G17DCTR triple buffer. Featuring three independent channels with built-in Schmitt-trigger inputs, this highly efficient IC excels at taking slow-rising, noisy, or distorted signals and converting them into sharp, crisp digital outputs. It is an invaluable component in environments with high electromagnetic interference (EMI), such as FPV drones with powerful brushless motors and noisy power systems.

Operating across a versatile supply range of 1.65V to 5.5V, its inputs are fully 5V-tolerant regardless of the VCC voltage. This makes it perfect for unidirectional level shifting (e.g., stepping down 5V telemetry signals to a safe 3.3V for an STM32 MCU). The three-channel configuration strikes the perfect balance for drone electronics, allowing you to buffer a UART line (TX/RX) and an addressable LED data line (like WS2812) all within a single, ultra-compact MSOP-8 package, saving precious PCB space.

Key Features:

• Schmitt-Trigger Inputs: Built-in hysteresis provides excellent noise immunity, transforming slow or degraded inputs into clean, jitter-free logic transitions.

• Three Independent Channels: The perfect channel count for buffering serial communication lines and lighting signals without wasting space on unused gates.

• 5V-Tolerant Inputs: Safely accepts 5V logic signals even when powered by a lower voltage like 3.3V, ideal for safe level shifting.

• Space-Saving Design: The miniature MSOP-8 footprint is significantly smaller than standard quad-buffers, making it ideal for densely packed flight controllers.
