Specifications

Description 

These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or mono-stable mode of operation, the Duty Cycle timed interval is controlled by a single external of operation, the frequency and duty cycle can be controlled independently with two external resistors terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If 2 Applications the trigger input is above the trigger level and the threshold input is above the threshold level, the flipflop is reset and the output is low.

The reset (RESET)  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.
