Timer/Counter 8-Pin PDIP N

The 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 I/O terminal. 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.
