Key Features
- 3.3 V supply operation with slew-rate limiting supporting data rates up to 10 Mbps on RS-485/RS-422 buses
- Differential Schmitt trigger receiver input provides high noise immunity for reliable operation in electrically noisy industrial environments
- Receiver remains active under shutdown mode, enabling bus monitoring without driving the line in half-duplex multi-node networks
Applications
The MAX3483CSA+T is well-suited for industrial fieldbus networks, building automation systems, and multi-drop serial communication links operating at 3.3 V. Its slew-rate-limited driver reduces electromagnetic interference (EMI) on long cable runs up to several hundred meters at low baud rates, making it appropriate for RS-485 networks in PLCs and HVAC controllers. The 8-SOIC package and 3.3 V operation simplify integration into modern low-voltage microcontroller-based designs.

Frequently Asked Questions
At what supply voltage and maximum data rate does the MAX3483CSA+T operate?
The MAX3483CSA+T operates from a 3.3 V supply and supports RS-485/RS-422 serial data rates up to 10 Mbps with slew-rate-limited driver outputs. The slew-rate limiting reduces electromagnetic interference on cable runs while maintaining reliable signal integrity across multi-node industrial bus networks.
How does the Schmitt trigger receiver input improve noise immunity in the MAX3483CSA+T?
The differential Schmitt trigger receiver input of the MAX3483CSA+T introduces hysteresis on the differential input threshold, rejecting noise spikes and slow signal transitions that would cause false triggering in a standard comparator-type receiver. This is especially effective on long RS-485 cable runs where reflected signals or coupled industrial noise exceed 200 mV.
Can the MAX3483CSA+T receiver remain active while the driver is disabled?
Yes. The MAX3483CSA+T includes a shutdown mode where the driver is tri-stated while 1 receiver remains active, allowing the device to monitor the RS-485 bus without transmitting. This is useful in half-duplex multi-node networks where nodes must listen continuously for bus activity between transmission events.
What package does the MAX3483CSA+T use, and how does it fit on a PCB?
The MAX3483CSA+T is housed in an 8-pin SOIC narrow (150 mil) surface-mount package occupying approximately 4.9 mm x 3.9 mm of PCB area. The compact 8-SOIC footprint integrates the full RS-485 transceiver function in a standard SMT package compatible with automated pick-and-place and reflow soldering processes.
