Pin Description
PIN
NAME
DESCRIPTION
1
TXD
Data Transmit Input, CMOS Compatible. TXD is internally pulled up to V_I/O.
2
GND
Ground
3
V_CC
Supply Voltage +4.75V to +5.25V. Bypass V_CC to ground with a 0.1µF ceramic capacitor as close as
possible to the device.
4
RXD
Data Receive Output, CMOS Compatible
5
V_I/O
Supply Voltage for I/O Level Translation, +2.8V < V_I/O < V_CC (see the Level Shifting section). Bypass
V_I/O to ground with a 0.1µF ceramic capacitor as close as possible to the device.
6
EN
Enable Input. Control the operating mode by driving EN logic-high or logic-low (see Table 1 and
Figure 4.)
7
INH
Inhibit Output. INH controls one or more external voltage regulators.
8
ERR
Error Output, Active Low. ERR indicates errors and displays status of internal flags.
9
WAKE Local Wake-Up Input. Present a voltage transition on WAKE to generate a local wake-up event.
10
V_BAT
Battery Voltage Input. Bypass V_BAT to ground with a 0.1µF ceramic capacitor as close as possible to
the device.
11
SPLIT
Split Termination Voltage Output. Connect SPLIT to the center node of two 60Ω termination resistors
to provide common-mode voltage stabilization (see Figure 3). SPLIT outputs a voltage of V_CC/2.
12
CANL Low-Level CAN Differential Bus Line
13
CANH High-Level CAN Differential Bus Line
14
STB
Standby Input, Active Low. Drive STB logic-high or logic-low to control the operating mode (see Table
1 and Figure 4.)
