Product Description
The PC-DIO-96/PnP is a 96-bit, parallel, digital I/O interface for ISA computers. Four 82C55A programmable peripheral interface (PPI) chips control the 96 bits of digital I/O. The 82C55A can operate in either a unidirectional or bidirectional mode and can generate interrupt requests to the host computer. You can program the 82C55A for almost any 8-bit or 16-bit digital I/O application. All digital I/O communication is through a standard, 100-pin, male connector. The PC-DIO-96/PnP also includes an 82C53 counter/timer that can send periodic interrupts to the host system.
