Technical Specifications

The MD82C54/883 operates from a single 5V power supply. It includes three independent 16-bit counters, each of which can be programmed to operate in one of six different modes. The modes include interrupt on terminal count, programmable one-shot, rate generator, square wave generator, hardware triggered strobe, and software triggered strobe. The device's counting frequency is determined by the external clock input. The military-grade version (/883) is tested and specified to operate over a wider temperature range, typically -55°C to +125°C. Further detailed specifications can be found in the manufacturer's datasheet.
