$1.04 Regular price:$2.59
Precision monolithic 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 may be independently controlled with two external resistors and a single external capacitor.
- The threshold and trigger levels are normally two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control voltage terminal.
