PIN FUNCTIONS
TXD (Pin 1): Transmit Data Input. Low in dominant state.
Integrated 500k pull-up to V
CC
.
GND (Pin 2): Ground.

CC
(Pin 3): Positive Supply. 3V ≤ V
CC
≤ 3.6V or 4.5V ≤

CC
≤ 5.5V. Bypass with 0.1µF ceramic capacitor or larger.
RXD (Pin 4): Receiver Data Output. Low in dominant
state. Integrated 500k pull-up to V
CC
.
SPLIT (Pin 5): Common Mode Stabilization Output for
Optional Split Termination. ±60V tolerant, 25kV ESD. If
unused, leave open.
CANL (Pin 6): Low Level CAN Bus Line. ±60V tolerant,
25kV ESD.
CANH (Pin 7): High Level CAN Bus Line. ±60V tolerant,
25kV ESD.
RS (Pin 8): Shutdown Mode/Slew Control Input. A voltage
on RS higher than V
IH_RS
puts the chip in a low power
shutdown state. A voltage on RS lower than V
IL_RS
enables the chip. A resistor between RS and ground can
be used to control the slew rate. See Applications section
for details.
GND (Pin 9): Exposed pad on the DFN package. Connect
to PCB ground.
