Functional Description • Dual Monostable Multivibrator TC74VHC123AF/AFK: Retriggerable TC74VHC221AF/AFK: Non-Retriggerable 2.
General The TC74VHC123A/221A are high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.
There are two trigger inputs, A input (negative edge), and B input (positive edge).
These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs.
This device may also be triggered by using CLR input (positive edge).
After triggering, the output stays in a MONOSTABLE state for a time period determined by the external resistor and capacitor (RX, CX).
A low level at the CLR input breaks this state.
Limits for CX and RX are: External capacitor, CX: No limit External resistor, RX: VCC = 2.
0 V more than 5 kΩ VCC ≥ 3.
0 V more than 1 kΩ An input protection circuit ...
