Note
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 rapidy, there will be some possibility of damaging the I.C. with a surge current or latch-up. If the voltage supply filter capacitor is large enough and VCC decrea... |
