Maxim MAX1483ESA 20µA Slew-Rate-Limited RS-485 Transceivers

Shenzhen Mingjiada Electronics Co., Ltd, as a global well-known electronic components distributor, supplies Maxim MAX1483ESA low-power RS-485/RS-422 transceiver chip from stock. This MAX1483ESA device is designed for industrial control, communication networks and other applications, with 20µA ultra-low operating current and swing limit characteristics, can effectively reduce EMI and signal reflection problems.

Product Description Of MAX1483ESA

MAX1483ESA is low-power transceivers for RS-485 communication. MAX1483ESA feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps.

MAX1483ESA draw only 20µA of supply current. Additionally, they have a low-current shutdown mode that consumes only 0.1µA.The parts operate from a single +5V supply.

Drivers is short-circuit current limited and are protected 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 the input is open circuit.

MAX1483ESA is half duplex, have a 1/8-unit-load input impedance that guarantees up to 256 transceivers on the bus.
