Application Circuit
Application Notes
The FXM2IC102 has open-drain outputs and requires pull-up resistors on the four data I/O pins, as shown in the above
figure. If a pair of data I/O pins (A
pull-down or pull-up resistors are not required.
The recommended values for the pull-up resistors (R
value for the bypass capacitors (C
or higher and may depend upon the current-sinking capability of the device driving the OE pin.
