Designed to provide a variety of configuration options, including software-programmable port directions and strobed I/O handshaking, the DIO96-104 digital I/O module offers 96 TTL/CMOS-compatible digital I/O channels arranged as four 24-bit groups. Each group is divided into three 8-bit ports and is controlled by a separate 82C55A peripheral interface chip. The I/O circuitry is designed without passive pull-up or pull-down resistors, allowing the user's application to individually dictate how each channel will be handled during reset and input modes. An optional J2/P2 connector provides 16-bit stack-through compatibility. List price is $119.
