Timer/Counter 16-Pin CDIP N

The ICM7250 are programmable timer/ counters . They require only 120µA of supply current, while generating delays from microseconds to days. Each device combines a counter with an internal oscillator whose period is controlled by an external resistor and capacitor. The oscillator can be inhibited and an external clock applied to the TB I/O terminal. The programmable counters in the ICM7250 can be programmed using thumbwheel switches, jumpers, and analog switches. The ICM7250 has a two digit programmable BCD counter and can generate time delays from 1 to 99 RC time constants. These four devices are easily cascaded and can operate in either astable or monostable configurations, using the on-chip control flip-flop with Trigger and Reset inputs.
