20Mbps, +3.3V, SOT23 RS-485/

RS-422 Transmitters

General Description

Features

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.

♦ Space-Saving 6-Pin SOT23 Package

♦ 250kbps/2.5Mbps/20Mbps Data Rates Available

♦ Operate from a Single +3.3V Supply

♦ ESD Protection

±9kV—Human Body Model

♦ Slew-Rate Limited for Errorless Data

Transmission (MAX3293/MAX3294)

♦ 1µA Low-Current Shutdown Mode

♦ -7V to +12V Common-Mode Input Voltage Range

The MAX3293/MAX3294/MAX3295 output level is guar-

anteed at +1.5V with a standard 54Ω load, compliant

with RS-485 specifications. The transmitter draws 5mA

of supply current when unloaded, and 1µA in low-

power shutdown mode (DE = GND).

♦ Current Limiting and Thermal Shutdown for

Driver-Overload Protection

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.

♦ Hot-Swap Inputs for Telecom Applications

♦ Automotive Temperature Range (-40°C to +125°C)

Ordering Information

The MAX3293/MAX3294/MAX3295 are offered in a

6-pin SOT23 package, and are specified over the

automotive temperature range.
