IO203

IO203 — The IO203 is a digital I/O module providing a total of 64 TTL channels.

Introduction

The IO203 is a digital I/O module providing a total of 64 TTL channels. The transceivers are TTL and CMOS/TTL compatible (5V/3.3V, ±24mA available for 3.3V usage only) and can also be set to be CMOS compliant by on-board jumper.

Each of the 64 channels can be individually programmed as an input or output. The 64 channels are arranged into two groups of 32. Each group is accessed via a single bus access cycle which leads to a simultaneous update of each group with very low latency.
