ANALOG DEVICES ICM7240IPE+

The ICM7240IPE+ is a programmable timer/ counter in 16 pin DIP package. It requires 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 ICM7240 can be programmed using a thumbwheel switches, jumpers and analogue switches. The ICM7240 has an 8bit programmable counter and can generate time delays from 1 to 255 RC time constants. It can be easily cascaded and can operate in either monostable and astable configurations using the on-chip control flip flop with trigger and reset inputs. The ICM7240 is suitable for wide variety of timing and control applications such as ON/OFF delay timers, batch timer/sequencers, cycle timers, programmable timers, frequency synthesizers and ultra long time delay generators.
