TERMINAL DEFINITIONS
A functional description of each terminal can be found in the System/Application Information section beginning on
page 18
.
Terminal

Name
Formal Name
Definition
1
RXD
Receive Data
CAN bus receive data output
2
TXD
Transmit Data
CAN bus transmit data input
3
V
DD
Voltage Digital Drain
5.0 V regulator output terminal.
4
RST
Reset Output
(Active LOW)
This is the device reset output whose main function is to reset the MCU. This terminal
has an internal pull-up current source to V
DD
5
INT
Interrupt Output
(Active LOW)
This output is asserted LOW when an enabled interrupt condition occurs. The output
is a push-pull structure.
6–9
20–23
GND
Ground
Ground of the IC. These terminals are connected to the package lead frame in order to
provide a thermal path.
10
V2
Voltage Source 2
Sense input for V2 regulator using external ballast. V2 is also the internal supply for the
CAN cell.
11
V2CTRL
Voltage Source 2 Control
Output driver for the external ballast transistor.
12
V
SUP
Voltage Supply
Supply input for the complete device.
13
HS
High-Side Output
Output of internal high-side switch. Current capability is internally limited to 150 mA.
14–17
L0–L3
Level 0–3 Inputs
Input interfaces to external circuitry (switched or ICs). Levels at these terminals can be
read by SPI and input can be used as programmable wake-up input in Sleep or Stop
mode.
18
CANH
CAN High
CAN high output.
19
CANL
CAN Low
CAN low output.
24
SCLK
Serial Data Clock
Clock input for the Serial Peripheral Interface (SPI) of the device.
25
MISO
Master In/Slave Out
SPI data sent to MCU. When
CS
is HIGH, terminal is high impedance.
26
MOSI
Master Out/Slave In
SPI data received by the 33742.
27
CS
Chip Select
(Active LOW)
Chip select terminal for SPI. When
CS
is LOW, device is selected.
28
WDOG
Watchdog Output
(Active LOW)
Output of watchdog circuitry. Terminal is asserted LOW if software watchdog is not
correctly triggered.
