TC74VHC221AFN - DUAL MONOSTABLE MULTIVIBRATOR
(1) Standby state The external capacitor (CX) is fully charged to VCC in the stand-by state.
That means, before triggering, the QP and QN transistors which are connected to the RX/CX node are in the off state.
Two comparators that relate to the timing of the output pulse, and two reference voltage s
