DESCRIPTION/ORDERING INFORMATION

These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the

time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and

capacitor network. In the astable 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 V_CC. 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.
