DATASHEET ICM7242 FN2866 Long Range Fixed Timer Rev 5.00 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 replace the 2242 in most applications, with a significant • Replaces the 2242 in Most Applications 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 Ordering Information • Wide Supply Voltage Range . 2V to 16V PARTPACKAGE • Low Supply Current . 115µA at 5V NUMBERPARTTEMP.(RoHSPKG. • Pb-Free Plus Anneal Available (RoHS Compliant) (See Note)MARKING RANGE (°C)Compliant)DWG. # ICM7242IPAZ 7242 IPAZ -25 to +85 8 Ld PDIP** E8.3 Pinout ICM7242CBAZ* 7242 CBAZ 0 to +70 8 Ld SOIC M8.15 ICM7242(No longer(8 LD PDIP, SOIC)available or TOP VIEW supported) ICM7242IBAZ* 7242 IBAZ -25 to +85 8 Ld SOIC M8.15 V18 TB I/O(No longerDDavailable or 2 OUT 27 RCsupported) 128/256 OUT 36 TRIGGER *Add “-T” suffix for tape and reel.

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 FN2866 Rev 5.00 Page 1 of 11 September 14, 2015
