Product Summary

The MSM82C54-2JS is a programmable universal timer designed for use in microcomputer systems. Based on silicon gate CMOS technology, the MSM82C54-2JS requires a standby current of only 10 mA (max.) when the chip is in the non-selected state. And during timer operation, the power consumption is still very low with only 10mA (max.) of current required. The MSM82C54-2JS consists of three independent counters, and can count up to a maximum of 10 MHz. The timer features six different counter modes, and binary count/BCD count functions. Count values can be set in byte or word units, and all functions are freely programmable.
