100 MHz frequency and period counter using the Intersil ICM7226B 40 pin DIP


Posted on Feb 6, 2014

100 MHz frequency and period counter using the Intersil ICM7226B 40-pin DIP. This circuit uses a CD4016 analog multiplexor to multiplex the digital outputs back to the function input. Since the CD4016 is a digitally controlled analog transmission gate no level shifting of the digital output is required. CD4051s or CD4052s could also be used to sel

ect the proper inputs for the multiplexed input on the ICM7226 from 2-or 3-bit digital inputs. These analog multiplexers could also be used in systems in which the mode of operation is controlled by a microprocessor rather than directly by front panel switches (courtesy Intersil, Inc. ).
