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.
Features
• t_wOUT = 10 ms ± 5% (at R_X = 100 kΩ C_X = 0.1 μF, V_DD = 10
V)

Note: In the case of using only one circuit, CD should be tied to GND, T₂, T₁, Q, Q should be tied to OPEN, and
the other inputs should be tied to V_CC or GND.
