HC4538 High-speed CMOS Dual Precision Monostable Multivibrator IC

HC4538 High-speed CMOS Dual Precision Monostable Multivibrator IC

The HC4538 monostable multivibrator (often referred to as a one-shot pulse generator) is used to generate precision pulses of fixed width, which can be controlled by external resistors and capacitors. It has two independent monostable multivibrators in a single package, with each half having a trigger input, reset input, and control options for pulse width timing. It operates with both rising-edge and falling-edge triggers, making it highly versatile for timing and pulse generation applications.
