Description

555 timer chips are precision timing circuits capable of producing accurate time delays or oscillation.

In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network.

In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.

The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC.

These levels can be altered by use of the control-voltage terminal.

When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high.

If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low.

The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle.

When RESET goes low, the flip-flop is reset, and the output goes low.

When the output is low, a low-impedance path is provided between discharge (DISCH) and ground.

The output circuit is capable of sinking or sourcing current up to 200 mA.

Operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs.
