74HCT221 multivibrator equivalent, dual non-retriggerable monostable multivibrator.
* Pulse width variance is typically less than ± 5%
* Pin-out identical to “123”
* Overriding reset terminates output pulse
* nB inputs have hysteresis for.
pulse stability will only be limited by the accuracy of the external timing components. The output pulse width is define.
The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT221 are dual non-retriggerable monostable multivibrators. Each mu.
