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_n/B_n) are not used, they both should be tied to Gnd (or both to V_CC). In this case,
pull-down or pull-up resistors are not required.
The recommended values for the pull-up resistors (R_PU) are 1kΩ minimum to 10kΩ maximum. The recommended
value for the bypass capacitors (C_BP) is 1.1µF. The recommended value for the pull-down resistor (R_PD) on OE is 1kΩ
or higher and may depend upon the current-sinking capability of the device driving the OE pin.
