74HC221DB - Brand New PHI Multivibrators
-
Description
The 74HC/HCT221 is a fast Si-gate CMOS device belonging to the Multivibrators product category. It is compatible with low power Schottky TTL (LSTTL) and complies with JEDEC standard no. 7A. This component is a dual non-retriggerable monostable multivibrator that has two enable inputs which can be used independently.
The pulse width variance is typically less than ±5%. The pin-out is identical to "123", and the overriding reset terminates the output pulse. The nB inputs have hysteresis for improved noise immunity. The output capability is standard, except for nREXT/CEXT. The ICC category is MSI.
