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 (R
X
) and the external capacitor (C
X
), it becomes
possible to set a broad range of output pulse widths.
