General Description

The MAX13050/MAX13052/MAX13053/MAX13054 are pin-

for-pin compatible, industry-standard, high-speed, control

area network (CAN) transceivers with extended ±80V fault

protection. These products are ideal industrial network

applications where overvoltage protection is required.

These CAN transceivers provide a link between the CAN

protocol controller and the physical wires of the bus lines in

a CAN. These devices can be used for DeviceNet

applications, requiring data rates up to 1Mbps.

The CAN transceivers have an input common-mode

range greater than ±12V, exceeding the ISO11898

specification of -2V to +7V, and feature ±8kV ESD pro-

tection, making these devices ideal for harsh industrial

environments.

The CAN transceivers provide a dominant timeout func-

tion that prevents erroneous CAN controllers from clamp-

ing the bus to a dominant level if the TXD input is held low

for greater than 1ms. The MAX13050/MAX13052 provide

a SPLIT pin used to stabilize the recessive common-

mode voltage. The MAX13052 also has a slope-control

mode that can be used to program the slew rate of the

transmitter for data rates of up to 500kbps. The

MAX13053 features a silent mode that disables the trans-

mitter. The MAX13053 also has a reference output that

can be used to bias the input of older CAN controllers

that have a differential comparator. The MAX13054 has a

separate dedicated logic input, V

CC2

, allowing interfacing

with a +3.3V microcontroller.

The MAX13050/MAX13052/MAX13053/MAX13054 are

available in an 8-pin SO package and are specified to

operate in the -40°C to +85°C and the -40°C to +125°C

temperature ranges.

MAX13050/MAX13052/MAX13053/MAX13054 Industry-Standard High-Speed CAN Transceivers with ±80V Fault Protection rates of up to 500kbps. This reduces the effects of EMI, thus allowing the use of unshielded-twisted or parallel cable. The MAX13050/MAX13052 and MAX13054 standby mode shuts off the transmitter and switches the receiver to a low-current/low-speed state.
