Advanced Micro Devices, Inc. D8212 Integrated Circuit

AMD D8212 is an 8-bit input/output port circuit built by Advanced Micro Devices and packaged in a ceramic DIP-24 (24-pin) form factor. It provides eight configurable I/O lines intended to interface a processor with peripheral signals or simple external devices, serving as a compact I/O interface in early microprocessor systems. The ceramic DIP-24 packaging identifies its through-hole, high-reliability construction, suitable for vintage boards or designs that require a dedicated 8-bit I/O port device in a compact package. As an AMD part designated D8212, this device is commonly cataloged as an I/O port circuit in older AMD literature and distributor listings, making it a recognized solution for projects that rely on 8-bit parallel I/O expansion in 24-pin ceramic packaging.
