... M74HC221 BLOCK DIAGRAM (1) Cx, Rx, Dx are external components. ( clamping diode. The external capacitor is charged to Vcc in the stand-by-state, i.e. no trigger. When the supply voltage is turned off scharged mainly trough an internal parasitic diode(see figures sufficiently large and Vcc decreases rapidly, there will be some possibility of damaging the I ...
