PIN FUNCTIONS
UU
U
A (Pin 6): Driver Output/Receiver Input. The input resis-
tance is typically 22k when the driver is disabled (DE = 0).
When the driver is enabled, the A output follows the logic
level at the DI pin.
B (Pin 7): Driver Output/Receiver Input. The input resis-
tance is typically 22k when the driver is disabled (DE = 0).
When the driver is enabled, the B output is inverted from
the logic level at the DI pin.
VCC (Pin 8): Positive Supply. 4.75V ≤ VCC ≤ 5.25V. A 0.1F
bypass capacitor is recommended.
