•Attached components
(1) Timing capacitors (Pins 2 and 6)
Connected between these pins and the ground (GND),
this capacitor determines the one-shot period. We rec-
ommend using a capacitor with a value greater than
1000pF. The one-shot cycle is determined by T = 1 / 2
C • R.
(2) Timing resistor (Pins 2 and 6)
Connected to the power supply line, these resistors
determine the one-shot period. The timing capacitor is
charged through this resistor. The recommended range
for the timing resistor is 10kΩ to 1MΩ.
(3) Power supply capacitor (Pin 8)
Connect a 0.02µF capacitor between the power supply
pin and the ground (GND) so as to prevent malfunction
resulting from a rise in the impedance of the power
supply line.
(4) Load (Pins 1 and 7)
A load of up to 5mA can be accommodated for both the
inflow current and the outflow current.
