3 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
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 Processing
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.
