TIP672

24 Differential I/O Lines with Interrupts

Application Information

The TIP672 is an IndustryPack® compatible module

providing 24 digital differential I/O lines using EIA-422 /

EIA-485

compatible

ESD

protected

line

driver

and

receiver. Each line can be individually configured as

differential input or differential output.

The differential receivers are always enabled, allows

determining the state of the I/O line at any time. This can

be used as read back function for lines configured as

outputs.

All 24 input lines can generate an interrupt. Each input

interrupt can individually be enabled and cleared. The

signal edge handling is programmable.

Configuring an I/O line as output enables the differential

transmitter and the I/O line reflects the state programmed

in the output register.

Optional the I/O lines can be configured for simultaneous

update internally and across several IP’s by an external

clock source. The polarity of the external clock source is

programmable.

6 resistor networks (4 x 120 ohms) mounted in sockets are

used to terminate the differential I/O lines. The resistor

networks can be removed or changed in value.

After power-on or reset all I/O lines are configured as input

and all pending interrupts are cleared.

Software Support (TIP672-SW-xx) is available for different

operating systems.
