TC4538BP, TC4538BF
TC4538BP/TC4538BF Dual Precision
Retriggerable/Resettable Monostable Multivibrator
The TC4538BP/BF is the retriggerable/resettable monostable
multivibrator and the trigger operation can be made at either the
leading or trailing edge by 2 inputs of A and B. Since the output
monostable pulse width is decided by time constant of the external
resistor (RX) and the external capacitor (CX), it becomes possible to
set a broad range of output pulse widths.
