Additional Details
The TMP82C59AP-2 operates from a single 5V power supply and is typically packaged in a 28-pin DIP (Dual In-line Package). The device is programmed through an 8-bit data bus and control signals. The operating temperature range is typically from 0°C to 70°C. The controller supports various interrupt modes, including fully nested, rotating, and special mask mode. The device can be cascaded with other TMP82C59AP-2 controllers to expand the number of interrupt inputs. The device is controlled through a set of control registers that are programmed by the host processor.
