General Description

The MAX3058/MAX3059 interface between the con-

troller area network (CAN) protocol controller and the

physical wires of the bus lines in a CAN. They are pri-

marily intended for printer and telecom backplane appli-

cations requiring data rates up to 1Mbps. These

devices provide differential transmit capability to the bus

and differential receive capability to the CAN controller.

The MAX3058 output common-mode range is from -7V

to +12V. The MAX3059 output common-mode range is

switch termination resistor that makes it ideal for JetLink

applications.

The MAX3058 features four different modes of opera-

tion: high speed, slope control, standby, and shutdown.

The MAX3059 features three different modes of opera-

tion: high speed, slope control, and shutdown. High-

speed mode allows data rates up to 1Mbps. In

slope-control mode, the slew rate may be optimized for

data rates up to 500kbps, so the effects of EMI are

reduced, and unshielded twisted or parallel cable can

be used. In standby mode, the transmitters are shut off

and the receivers are put into low-current mode. In

shutdown mode, the transmitter and receiver are

switched off.

The MAX3058/MAX3059 are available in an 8-pin SO

package and are specified over the -40

°C to +125°C

temperature range.
