Таймеры и сопутствующая продукция ICM7242IPA+

Таймер , кварцевый генератор и генератор импульсов, фиксированный таймер / счетчик, 15МГц, 2В до 16В

The ICM7242IPA+ is a fixed timer/ counter in 8 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 ICM7242 has an 8bit fixed counter and can generate time delays from 1 to128 RC time constants. It can be easily cascaded and can operate in monostable and astable configurations using the on-chip control flip flop with trigger and reset inputs. The ICM7242 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.
