Description |
| 1,13 |
Discharge |
Open collector output which discharges a capacitor between intervals (in phase with output). 7 I It toggles the output from high to low when voltage reaches 2/3 of the supply voltage |
| 2,12 |
Threshold |
Compares the voltage applied to the terminal with a reference voltage of 2/3 Vcc. The 6 I amplitude of voltage applied to this terminal is responsible for the set state of the flip-flop |
| 3,11 |
Control Voltage |
Controls the threshold and trigger levels. It determines the pulse width of the output 5 Voltage I waveform. An external voltage applied to this pin can also be used to modulate the output waveform |
| 4,10 |
Reset |
Negative pulse applied to this pin to disable or reset the timer. When not used for reset 4 I purposes, it should be connected to VCC to avoid false triggering |
| 5,9 |
Out |
This pin is normally connected to load as it is the only pin with output driven waveform |
| 6,8 |
Trigger |
Responsible for transition of the flip-flop from set to reset. The output of the timer depends 2 I on the amplitude of the external trigger pulse applied to this pin |
| 7 |
Ground |
Ground Reference Voltage 0V |
| 14 |
Vcc |
Supply Voltage (Typical = 5V, Maximum = 18V) |
