Design a Custom BoardAbout This Component
Precision timing circuit capable of generating accurate time delays or oscillation in monostable or astable modes. Output can source or sink up to 200mA and is TTL-compatible. Timing intervals are controlled by external resistor-capacitor networks, enabling applications in pulse generation, frequency division, and industrial control circuits.
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.
