Description

This IC provides a highly accurate 555 Timer circuit that is capable of producing both time delays or oscillation. It is in a single 8 pin DIL package and can be operated in astable or monostable mode with external (RC) timing control.

The 555 timer is a simple circuit. By taking the trigger signal from high to low the flip-flop is set. This causes the output to go high and the discharge pin to be released from GND (0V). The releasing of the discharge pin from GND causes an external capacitor to begin charging. When the capacitor is charged the voltage across it increases. This results in the voltage on the threshold pin increasing. When this is high enough it will result in the flip-flop to resetting. This causes the output to go low and the discharge pin is also taken back to GND. This discharges the external capacitor ready for the next time the device is triggered.

Pin.Information.
V+Supply Voltage
GNDGND (0V) connection for supply voltage
ThresholdActive high input pin that is used to monitor the charging of the timing capacitor
Control VoltageUsed to adjust the threshold voltage if required. This should be left disconnected if the function is not required. A 0.01uF capacitor to GND can be used in electrically noisy circuits
TriggerActive low trigger input that starts the timer.
DischargeOutput pin that is used to discharge the timing capacitor
OutTimer output pin
ResetActive low reset pin. Normally connected to V+ if the reset function is not required
