General Description
The MAX13410E–MAX13415E are half-duplex RS-485-/RS-
422-compatible transceivers optimized for isolated appli-
cations. These devices feature an internal low-dropout
regulator (LDO), one driver, and one receiver. The inter-
nal LDO allows the part to operate from an unregulated
power supply of up to 28V. The AutoDirection feature
reduces the number of optical isolators needed in isolat-
ed applications. Other features include enhanced ESD
protection, fail-safe circuitry, slew-rate limiting, and full-
speed operation.
The MAX13410E–MAX13415E internal LDO generates a
5V ±10% power supply that is used to power its internal
circuitry. The MAX13412E–MAX13415E bring the 5V to an
output VREG that allows the user to power additional
external circuitry with up to 20mA to further reduce exter-
nal components. The MAX13410E/MAX13411E do not
have a 5V output and come in industry-compatible
pinouts. This allows easy replacement in existing designs.
The MAX13410E–MAX13415E feature a 1/8-unit load
receiver input impedance, allowing up to 256 trans-
ceivers on the bus. All driver outputs are ESD protected
using the Human Body Model. These devices also
include fail-safe circuitry (MAX13410E/MAX13411E/
MAX13414E/MAX13415E only), guaranteeing a logic-
high receiver output when the receiver inputs are open
or shorted. The receiver outputs a logic-high when the
transmitter on the terminated bus is disabled (high
impedance).
The MAX13412E/MAX13413E feature Maxim’s propri-
etary AutoDirection control. This architecture eliminates
the need for the DE and RE control signals. In isolated
applications, this reduces the cost and size of the sys-
tem by reducing the number of optical isolators required.
The MAX13410E/MAX13412E/MAX13414E feature
reduced slew-rate drivers that minimize EMI and reduce
reflections caused by improperly terminated cables,
allowing error-free transmission up to 500kbps. The
MAX13411E/MAX13413E/MAX13415E are not slew-rate
limited, allowing transmit speeds up to 16Mbps.
The MAX13410E–MAX13415E are available in an 8-pin
SO package with an exposed paddle to improve power
dissipation, and operate over the extended -40°C to
+85°C temperature range.
