Additional Details

The MSM82C54-2GS-K operates from a single +5V power supply and features TTL compatible inputs and outputs for easy interfacing with other digital logic circuits. Each of the three 16-bit counters can be programmed independently to operate in different modes, making it suitable for a diverse set of timing and counting applications. The device utilizes a control register, which is accessed by the microprocessor to configure the operating mode and initial count value for each counter. The counters can be programmed to count in either binary or BCD format, further enhancing its adaptability. The device package is designed for easy integration into printed circuit boards (PCBs). Its programmable features and robust design make it a reliable solution for applications requiring precise timing and counting control.
