The 74HC4538D is a high-speed CMOS dual monostable multivibrator manufactured by Toshiba. It utilizes silicon gate C2MOS technology to achieve high-speed operation while maintaining low power dissipation. This device features two trigger inputs, A (positive edge) and B (negative edge), which are Schmitt trigger inputs, allowing for slow rise/fall time signals. The output remains in a monostable state for a period determined by external resistor and capacitor components.
Key electrical characteristics include a typical propagation delay of 25 ns at 5V, low standby current of 4.0 µA (max), and active current of 350 µA (max). It operates across a wide voltage range of 2.0 V to 6.0 V. The device is available in a 16-SOIC package and is suitable for surface mounting.
This dual monostable multivibrator is designed with protection circuits on all inputs against static discharge or transient excess voltage. The 74HC4538D is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
