MAX3058 Datasheet, PDF (1/12 Pages) Maxim Integrated Products – 5V, 1Mbps, Low Supply Current CAN Transceivers

19-2939; Rev 1; 9/03
5V, 1Mbps, Low Supply Current
CAN Transceivers
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
from 0V to V_CC. The MAX3059 contains an internal
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.
