Overview: ICM7242
Long Range Fixed Timer 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. Ordering Information PART NUMBER (See Note) PACKAGE PART TEMP. (RoHS PKG.

They are not intended for use in Reflow solder processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020 DATASHEET FN2866 Rev 5.
