MAX13050/MAX13052/MAX13053/MAX13054
Industry-Standard High-Speed CAN
Transceivers with ±80V Fault Protection

Detailed Description
The MAX13050/MAX13052/MAX13053/MAX13054
±80V fault-protected CAN transceivers are ideal for
industrial network applications where overvoltage pro-
tection is required. These devices provide a link
between the CAN protocol controller and the physical
wires of the bus lines in a control area network (CAN).
These devices can be used for DeviceNet applications,
requiring data rates up to 1Mbps.
The MAX13050/MAX13052/MAX13053/MAX13054
dominant timeout prevents the bus from being blocked
by a hungup microcontroller. If the TXD input is held
low for greater than 1ms, the transmitter becomes dis-
abled, driving the bus line to a recessive state. The
MAX13054 +3.3V logic input allows the device to com-
municate with +3.3V logic, while operating from a +5V
supply. The MAX13050 and MAX13052 provide a split
DC-stabilized voltage. The MAX13053 has a reference
output that can be used to bias the input of a CAN con-
troller’s differential comparator.
All devices can operate up to 1Mbps (high-speed
mode). The MAX13052 slope-control feature allows the
user to program the slew rate of the transmitter for data

NAME
FUNCTION
1
TXD
Transmit Data Input. TXD is a CMOS/TTL-compatible input from a CAN controller
with a 25k
pullup to VCC. For the MAX13054, TXD is pulled to VCC2.
2
GND
Ground
33
3
VCC
Supply Voltage. Bypass VCC to GND with a 0.1F capacitor.
4
RXD
Receive Data Output. RXD is a CMOS/TTL-compatible output from the physical
bus lines CANH and CANL. For the MAX13054, RXD output voltage is referenced
to the VCC2 supply voltage.
5
SPLIT
Common-Mode Stabilization Output. Output equaled to 0.5 x VCC. SPLIT goes
high impedance in standby mode .
6
CANL
CAN Bus-Line Low
7
CANH
CAN Bus-Line High
8
8
STBY
Standby Input. Drive STBY low for high-speed operation. Drive STBY high to
place the device in low-current standby mode.
—8
RS
Mode-Select Input. Drive RS low or connect to GND for high-speed operation.
Connect a resistor between RS and GND to control output slope. Drive RS high to
put into standby mode.
5
REF
Reference Output Voltage. Always on reference output voltage, set to 0.5 x VCC.
——
8
S
Silent-Mode Input. Drive S low to enable TXD and to operate in high-speed
mode. Drive S high to disable the transmitter.
——
5
VCC2
Logic-Supply Input. VCC2 is the logic supply voltage for the input/output between
the CAN transceiver and microprocessor. VCC2 allows fully compatible +3.3V
logic on all digital lines. Bypass to GND with a 0.1F capacitor. Connect VCC2 to
VCC for 5V logic compatibility.
