The MAX483CUA+T is a low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

Specifications:

• Manufacturer: Maxim Integrated
• Type: RS-485/RS-422 Transceiver
• Package: 8-pin µMAX (UMAX)
• Operating Voltage: +4.75V to +5.25V
• Data Rate: Up to 2.5Mbps
• Number of Drivers/Receivers: 1 Driver, 1 Receiver
• Operating Temperature Range: 0°C to +70°C
• ESD Protection: ±15kV (Human Body Model)
• Supply Current (Quiescent): 120µA (Max)
• Receiver Input Impedance: ≥12kΩ
• Driver Output Short-Circuit Current Limit: ±250mA

Descriptions:

• The MAX483CUA+T is designed for half-duplex communication in RS-485/RS-422 networks.
• It features reduced slew-rate drivers to minimize EMI and reflections in unterminated cables.
• Suitable for low-power applications due to its low quiescent current.

Features:

• Low Power Consumption: 120µA quiescent current.
• Slew-Rate Limited: Reduces EMI and signal reflections.
• Extended Common-Mode Range: ±7V for robust noise immunity.
• Thermal Shutdown Protection: Prevents damage from excessive power dissipation.
• Receiver Fail-Safe: Ensures a logic-high output when inputs are open or shorted.
• Compatible with 3.3V and 5V Systems.

This transceiver is commonly used in industrial control, building automation, and point-to-point data transmission systems.
