MULTI-FUNCTION I/O DRIVER
GENERAL DESCRIPTION
The IS31IO7328 2-wire serial-interfaced peripheral
features 8 I/O ports. Ports are divided into four push
pull I/Os and four open-drain I/Os and transition
detection.
Any of the 8 I/O ports can be configured as an input or
an output. All I/O ports configured as inputs are
continuously monitored for state changes (transition
detection). State changes are indicated by the INT_______
output. The interrupt is latched, allowing detection of
transient changes. When the IS31IO7328 is
subsequently read through the serial interface, any
pending interrupt is cleared.
The open-drain outputs are rated to sink 20mA at
0.22V headroom, and are capable of driving LEDs.
________
The RST input clears the serial interface, terminating
any I2C communication to or from the IS31IO7328. The
IS31IO7328 uses two address inputs to allow 2 I2C
slave addresses. The slave address also determines
the power-up logic state for the I/O ports.
