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.

*Add “-T” suffix for tape and reel.
**Pb-free PDIPs can be used for through hole wave solder processing
only. 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
