The ICM7242 is a CMOS timer/counter circuit consisting of an RC oscillator followed by an 8-bit binary counter. It will replace the 2242 in most applications, with a significant reduction in the number of external components.

Three outputs are provided. They are the oscillator output, and buffered outputs from the first and eighth counters.


Design Tip

Which of your RTC devices will not enter a high current state upon power down, like the X1286?
