74HCT221 Overview
The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. The 74HC/HCT221 are dual non-retriggerable monostable multivibrators.
74HCT221 Key Features
- Pulse width variance is typically less than ± 5%
- Pin-out identical to “123”
- Overriding reset terminates output pulse
- nB inputs have hysteresis for improved noise immunity
- Output capability: standard (except for nREXT/CEXT)
- ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin patible with low p
