General Description
The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected,
RS-485/RS-422 transceivers feature one driver and one
receiver. These devices include fail-safe circuitry, guar-
anteeing a logic-high receiver output when receiver
inputs are open or shorted. The receiver outputs a logic
high if all transmitters on a terminated bus are disabled
(high impedance). The MAX3070E–MAX3079E include a
hot-swap capability to eliminate false transitions on the
bus during power-up or hot insertion.
The MAX3070E/MAX3071E/MAX3072E feature reduced
slew-rate drivers that minimize EMI and reduce reflec-
tions caused by improperly terminated cables, allowing
error-free data transmission up to 250kbps. The
MAX3073E/MAX3074E/MAX3075E also feature slew-
rate-limited drivers but allow transmit speeds up to
500kbps. The MAX3076E/MAX3077E/MAX3078E driver
slew rates are not limited, making transmit speeds up to
16Mbps possible. The MAX3079E slew rate is pin
selectable for 250kbps, 500kbps, and 16Mbps.
The MAX3072E/MAX3075E/MAX3078E are intended for
half-duplex communications, and the MAX3070E/
MAX3071E/MAX3073E/MAX3074E/MAX3076E/MAX307
7E are intended for full-duplex communications. The
MAX3079E is selectable for half-duplex or full-duplex
operation. It also features independently programmable
receiver and transmitter output phase through
separate pins.
The MAX3070E–MAX3079E transceivers draw 800μA
of supply current when unloaded or when fully loaded
with the drivers disabled. All devices have a 1/8-unit
load receiver input impedance, allowing up to 256
transceivers on the bus.
