Note (1) CX, RX, DX are external components. (2) DX is a 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 CX is discharged mainly through an internal parasitic diode. If CX is sufficiently large and VCC decreases rapi... |
