1 Timing From Microseconds to Hours Astable or Monostable Operation Adjustable Duty Cycle TTL-Compatible Output Can Sink or Source Up To 00 ma 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 SLFS0D SEPTEMBER 9 REVISED JUNE 00 NE...D, P, PS, OR PW PACKAGE SA...D OR P PACKAGE SE...

9 APPLICATION INFORMATION SLFS0D SEPTEMBER 9 REVISED JUNE 00 monostable operation For monostable operation, any of these timers can be connected as shown in Figure 9. If the output is low, application of a negative-going pulse to the trigger (TRIG) sets the flip-flop (Q goes low), drives the output high, and turns off Q. Capacitor C then is charged through R A until the voltage across the capacitor reaches the threshold voltage of the threshold (THRES) input. If TRIG has returned to a high level, the output of the threshold comparator resets the flip-flop (Q goes high), drives the output low, and discharges C through Q. VCC ( V to V) RA = 9. kω CL = 0.0 µf RL = kω See Figure 9 RA Input 8 CONT VCC RESET DISCH OUT THRES TRIG GND RL Output Voltage V/div Input Voltage Output Voltage Capacitor Voltage Pin numbers shown are for the D, JG, P, PS, and PW packages. Figure 9. Circuit for Monostable Operation Monostable operation is initiated when TRIG voltage falls below the trigger threshold. Once initiated, the sequence ends only if TRIG is high at the end of the timing interval. Because of the threshold level and saturation voltage of Q, the output pulse duration is approximately t w =.R A C. Figure is a plot of the time constant for various values of R A and C. The threshold levels and charge rates both are directly proportional to the supply voltage, V CC. The timing interval is, therefore, independent of the supply voltage, so long as the supply voltage is constant during the time interval. Applying a negative-going trigger pulse simultaneously to RESET and TRIG during the timing interval discharges C and reinitiates the cycle, commencing on the positive edge of the reset pulse. The output is held low as long as the reset pulse is low. To prevent false triggering, when RESET is not used, it should be connected to V CC. Output Pulse Duration s tw Time 0. ms/div Figure 0.

10 SLFS0D SEPTEMBER 9 REVISED JUNE 00 astable operation APPLICATION INFORMATION As shown in Figure, adding a second resistor, R B, to the circuit of Figure 9 and connecting the trigger input to the threshold input causes the timer to self-trigger and run as a multivibrator. The capacitor C charges through R A and R B and then discharges through R B only. Therefore, the duty cycle is controlled by the values of R A and R B. This astable connection results in capacitor C charging and discharging between the threshold-voltage level ( 0. V CC ) and the trigger-voltage level ( 0. V CC ). As in the monostable circuit, charge and discharge times (and, therefore, the frequency and duty cycle) are independent of the supply voltage. 0.0 µf VCC ( V to V) ÏÏÏÏ RA = k RL = k ÏÏÏÏ RB = k See Figure C = 0. µf RA RB C Open (see Note A) 8 CONT VCC RESET DISCH OUT THRES TRIG GND RL Output Voltage V/div t H tl Output Voltage Pin numbers shown are for the D, JG, P, PS, and PW packages.

12 SLFS0D SEPTEMBER 9 REVISED JUNE 00 missing-pulse detector APPLICATION INFORMATION The circuit shown in Figure can be used to detect a missing pulse or abnormally long spacing between consecutive pulses in a train of pulses. The timing interval of the monostable circuit is retriggered continuously by the input pulse train as long as the pulse spacing is less than the timing interval. A longer pulse spacing, missing pulse, or terminated pulse train permits the timing interval to be completed, thereby generating an output pulse as shown in Figure.
