SN74221N TI Dual Monostable Multivibrator | 16-PDIP | 20ns Propagation Delay

Product Overview

The SN74221N is a dual monostable multivibrator from Texas Instruments, featuring two independent monostable circuits with Schmitt-trigger inputs. Housed in a 16-pin PDIP package, it provides precise pulse width control via external resistors and capacitors. With a typical propagation delay of 20 ns and wide supply voltage range (4.75 V to 5.25 V), it is ideal for timing and pulse shaping applications in industrial and consumer electronics.
