DATA SHEET PCF8575C Remote 16-bit I/O expander for I
... This quasi-bidirectional I/O can be used as an input or output without the use of a control signal for data direction. At power-on all the I/Os are in 3-state mode. The strong pull-up to VDD (IOHt) allows a fast rising edge into a heavily loaded output. This strong pull-up turns on when the output i ...
