Texas Instruments CD74HC221 High Speed CMOS Logic Dual Monostable Multivibrators with Reset CD74HC221PWT

The CD74HC221PWT is a dual monostable multivibrator with reset functionality, designed using high-speed CMOS logic. It features separate reset inputs and allows for output pulse widths to be adjusted through external resistor (RX) and capacitor (CX) components, providing flexibility in timing applications. The device supports both leading-edge and trailing-edge triggering, ensuring versatility in various circuit designs. It operates over a wide temperature range of -55¬8C to 125¬8C and is compatible with standard LSTTL logic levels, making it suitable for interfacing with other digital components. The IC is housed in a 16-lead TSSOP package, which is advantageous for space-constrained applications. The minimum external resistance is typically 500,Ѷ, and the minimum capacitance is 0pF, with pulse width calculated as tW = 0.7 RXCX at VCC = 4.5V. This product is ideal for engineers seeking reliable timing solutions in their designs.
