General Description
The MAX3293/MAX3294/MAX3295 low-power, high-
speed transmitters for RS-485/RS-422 communication
operate from a single +3.3V power supply. These
devices contain one differential transmitter. The
MAX3295 transmitter operates at data rates up to
20Mbps, with an output skew of less than 5ns, and a
guaranteed driver propagation delay below 25ns. The
MAX3293 (250kbps) and MAX3294 (2.5Mbps) are
slew-rate limited to minimize EMI and reduce reflections
caused by improperly terminated cables.
The MAX3293/MAX3294/MAX3295 output level is guar-
anteed at +1.5V with a standard 54
load, compliant
with RS-485 specifications. The transmitter draws 5mA
of supply current when unloaded, and 1μA in low-
power shutdown mode (DE = GND).
Hot-swap circuitry eliminates false transitions on the data
cable during circuit initialization or connection to a live
backplane, and short-circuit current limiting and thermal-
shutdown circuitry protect the driver against excessive
power dissipation.
The MAX3293/MAX3294/MAX3295 are offered in a
6-pin SOT23 package, and are specified over the
automotive temperature range.
