Additional Information

  • Summary

  • Reviews
Your source for precision timers.
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.
  • Maximum supply voltage, VCC: 18V
  • Output current, IO: ±225 mA
  • Input voltage, VI: CONT, RESET, THRES, TRIG - VCC
  • D package: 97
    P package: 85
  • Operating virtual junction temperature, TJ: 150°C
  • Case temperature for 60s FK package: 260°C
  • Lead temperature 1, 6mm (1/16") from case for 60s JG package: 300°C
  • Storage temperature range, Tstg: 65°-150°C
