3.3V-Powered, ±15kV ESD-Protected, 12Mbps and
Slew-Rate-Limited True RS-485/RS-422 Transceivers
General Description
Devices in the MAX3483E family (MAX3483E/MAX3485E/
MAX3486E/MAX3488E/MAX3490E/MAX3491E) are
±15kV ESD-protected, +3.3V, low-power transceivers for
RS-485 and RS-422 communications. Each device con-
tains one driver and one receiver. The MAX3483E and
MAX3488E feature slew-rate-limited drivers that minimize
EMI and reduce reflections caused by improperly termi-
nated cables, allowing error-free data transmission at
data rates up to 250kbps. The partially slew-rate-limited
MAX3486E transmits up to 2.5Mbps. The MAX3485E,
MAX3490E, and MAX3491E transmit at up to 12Mbps.
All devices feature enhanced electrostatic discharge
(ESD) protection. All transmitter outputs and receiver
inputs are protected to ±15kV using IEC 1000-4-2 Air-
Gap Discharge, ±8kV using IEC 1000-4-2 Contact
Discharge, and ±15kV using the Human Body Model.
Drivers are short-circuit current limited and are protect-
ed against excessive power dissipation by thermal
shutdown circuitry that places the driver outputs into a
high-impedance state. The receiver input has a fail-safe
feature that guarantees a logic-high output if both
inputs are open circuit.
The MAX3488E, MAX3490E, and MAX3491E feature
full-duplex communication, while the MAX3483E,
MAX3485E, and MAX3486E are designed for half-
duplex communication.
