DATASHEET ICM7242 FN2866 Rev 5.00 Long Range Fixed Timer September 14, 2015 The ICM7242 is a CMOS timer/counter circuit consisting of Features an RC oscillator followed by an 8-bit binary counter. It will Replaces the 2242 in Most Applications replace the 2242 in most applications, with a significant reduction in the number of external components. Timing From Microseconds to Days Three outputs are provided. They are the oscillator output, Cascadable and buffered outputs from the first and eighth counters. Monostable or Astable Operation Wide Supply Voltage Range . 2V to 16V Ordering Information PART PACKAGE Low Supply Current 115A at 5V NUMBER PART TEMP. (RoHS PKG.
