Additional Details

The TMP82C55AM-2 operates from a single 5V power supply and is fully TTL compatible, making it easy to integrate into existing digital systems. The device is programmed via an 8-bit data bus and control signals. The typical operating temperature range is between 0°C and 70°C. It is generally packaged in a 40-pin DIP (Dual In-line Package). Each of the three ports (A, B, and C) can be independently programmed to function as either an input or output. Port C provides the additional feature of setting or resetting individual bits under software control. This makes it a robust and versatile device for many applications requiring peripheral control in microcomputer systems.
