Product specification
Remote 16-bit I/O expander for I

C-bus
PCF8575
Notes
1.
The power-on reset circuit resets the I
2
C-bus logic with V
DD
< V
POR
and sets all I/Os to logic 1 (with current source
to V
DD
).
The value is not tested, but verified on sampling basis.
A single LOW-level output current (I
OL
) must not exceed 20 mA for an extended time. The sum of all I
OLs
at any point
in time must not exceed 100 mA.
