Digital IO Port Datasheet
Introduction
The Digital I/O Port provides 16 digital input/output signals at 5-volt logic levels. Up to four Digital I/O Ports
2
may be connected to a single I C Bus, giving up to 64 digital I/O channels per bus.
If more than four ports are required on a single bus, alternative driver chips (PCF8574A) can be fitted to the
extra ports, giving a maximum of eight ports (128 I/Os) per bus.
The Digital I/O Port plugs directly into one of the I2C Bus connectors on an Application Board.
Connection to the digital port signals is via a 20 way 0.1” MOLEX 6410 header or via the prototyping area
(60mm square).
