Design a Custom BoardAbout This Component
Single precision timer IC capable of generating stable timing pulses for astable and monostable modes up to 100kHz. Features adjustable frequency and duty cycle through external resistors and capacitors. Widely used in oscillators, pulse generators, frequency dividers, and timing circuit applications in industrial and consumer electronics.
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.
