Wish you: good luck in the New Year, as always, two people together, a family of three, the four seasons sings, five blessings,, 7 up to wealth, fortune and Yang auspicious, very happy!

An overview of the

Equipment MAX3483E family (MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E) plus or minus 15 kv ESD - protected, + 3.3 v, low power consumption for the rs - 485 and rs - 485 transceiver communication. Each device contains a driver and a receiver. MAX3483E and slew rate - limited - driver MAX3488E features, reduce the electromagnetic interference, reduce the reflection caused by the improper termination of the cable, allowing error data transmission data rate of 250 KBPS. Part of the slew rate - limited MAX3486E 2.5 MBPS. MAX3485E MAX3490E, MAX3491E transport up to 12 MBPS.

All the equipment function of electrostatic discharge (ESD) protection. All of the transmitter and receiver output to input protection + 15 kv using IEC 1000-4-2 air gap discharge, use of IEC 1000-4-2-8 kv contact discharge and + 15 kv model using the human body.

The driver is short circuit current limit, to prevent excessive thermal shutdown circuit power consumption, the driver output is high impedance state. Receiver input fail-safe function, to ensure a high logic output if the input.

MAX3490E, MAX3488E MAX3491E full-duplex communication function, although MAX3483E, MAX3485E, MAX3486E designed for half duplex communication.
