Design a Custom BoardAbout This Component
Precision timing circuit capable of astable or monostable operation with timing intervals from microseconds to hours. Output stage sources or sinks up to 200mA with TTL compatibility. Commonly used for pulse generation, frequency division, PWM, and industrial control applications with 5V to 15V supply operation.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
