|Pin Number||Pin Name||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)|
