We are trying to use the TSC2007 along with an I2C port expander with sharing the interupt of these two devices into our MCU...
We are experiencing an issue where the TSC2007 appears to be 'driving' (i.e. the PENIRQ appears to be push-pull) the PENIRQ pin high and thus, causing the I2C Port Expander interupt to fail...
IS the PENIRQ pin of the TSC2007 OPEN COLLECTOR/DRAIN ?
OR is it actually push-pull?
The spec doesn't actually say.... does it?
