... MSM82C53-2RS/GS/JS CMOS PROGRAMMABLE INTERVAL TIMER GENERAL DESCRIPTION The MSM82C53-2RS/GS/JS is programmable universal timers designed for use in microcomputer systems. Based on silicon gate CMOS technology, it requires a standby current of only 100 mA (max.) when the chip is in the nonselected state. During timer operation, power consumption is still very low only 8 mA (max MHz of current required. ...
