The importance Pins look at the table below.ġ.) Pin 16 is positive power supply and pin 8 is a ground. Positive supply voltage, which is usually between 3 and 15 V depending on the variation. Open collector output which may discharge a capacitor between intervals. The timing (OUT high) interval ends when the voltage at threshold is greater than that at CTRL (2/3 Vcc if CTRL is open). Provides “control” access to the internal voltage divider (by default, 2/3 Vcc). Overrides TRIG which overrides threshold. This output is driven to approximately 1.7 V below +Vcc, or to GND.Ī timing interval may be reset by driving this input to GND, but the timing does not begin again until RESET rises above approximately 0.7 volts. Output of the timer totally depends upon the amplitude of the external trigger voltage applied to this pin. In other words, OUT is high as long as the trigger low. The OUT pin goes high and a timing interval starts when this input falls below 1/2 of CTRL voltage (which is typically 1/3 Vcc, CTRL being 2/3 Vcc by default if CTRL is left open).
