The Maxim ICM7240/50/60 are programmable timer/ counters and the Maxim ICM7242 is a fixed timer/ counter. 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 1/0 terminal. The programmable counters in the ICM7240/50/60 can be programmed using thumbwheel switches, jumpers, and analog switches.
The ICM7240 has an 8 bit programmable counter and can generate time delays from 1 to 255 RC time constants. The ICM7250 has a two digit programmable BCD counter and can generate time delays from 1 to 99 RC time constants. The ICM7260 is used for "real time" applications and has a modulo 60 programmable divider, producing time delays from 1 to 59 RC time constants. The ICM7242 has an 8 bit fixed counter and can generate a time delay of 1 and 128 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.
