The 74HC4538D from Toshiba is a high-speed CMOS dual monostable multivibrator fabricated using silicon gate C2MOS technology. It achieves high-speed operation while maintaining low power dissipation, similar to LSTTL equivalents. This device features two trigger inputs, A (positive edge) and B (negative edge), which are valid for slow rise/fall time signals due to their Schmitt trigger nature.
The output remains in a monostable state for a time period determined by external resistor (RX) and capacitor (CX) components. A low level at the CD input can break this stable state. The device supports retriggering, where a new trigger during the monostable period extends the duration.
Key electrical characteristics include a typical propagation delay of 25 ns at 5V, a wide operating voltage range from 2V to 6V, and low power consumption with standby current at 4.0 µA (max) and active current at 350 µA (max) at 25°C.
The 74HC4538D is available in a 16-SOIC surface mount package. It is suitable for applications requiring precise timing control and pulse generation.
