TIP675 48 TTL I/O Lines with Interrupts

Application Information

The TIP675 is an IndustryPack® compatible module

providing 48 digital TTL tri-state I/O lines with pull up

resistors. Each of the 48 I/O lines is ESD protected and

protected against overvoltage.

The line inputs 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 48 input lines can generate an interrupt. Each input

interrupt

can

individually

be

enabled

and

cleared.

Interrupts for negative and positive transitions could be

used together with separate interrupt pending registers.

All interrupt inputs have an electronic debounce circuit to

prevent short spikes on input lines to cause an IP

interrupt.

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 mounted in sockets are used to pull

the tri-state I/O lines to a logic high value. 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 (TIP675-SW-xx) is available for different

operating systems.
