Design a Custom BoardAbout This Component
Single-channel microprocessor supervisory circuit in 5-pin SSOP package. Monitors power supply voltage and generates reset signals when supply drops below threshold. Typical applications include processor reset control, watchdog functions, and system power-on reset sequencing in microcontroller-based designs.
Package: SC-74A-5 · 5 pins
Why does this need a breakout?
Tiny 0.95mm pitch SMD makes hand-soldering risky and breadboarding impossible. A breakout board brings these single-gate logic ICs and analog switches to standard 0.1" headers, enabling rapid prototyping and reliable connections without microscopy skills or rework tools.
