Summary:
The MAX3250 is a 3.0V to 5.5V, ±50V isolated EIA/TIA-232 and V.28/V.24 communication interface chip that provides high-speed data transfer. The MAX3250 is a dual-die device that allows a ±50V drop across the RS-232 side and the logic side (ISOCOM and GND), making it capable of operating in noise environments with high common-mode voltages. This feature can avoid chip damage if the RS-232 line is shorted to a +24V or ±48V supply due to chance.
Key Features ±50V Isolation Shutdown Mode Supply Current 20μA
Ensure a data rate of 250kbps
/FAULT Output Shutdown Mode Transmitter and Receiver Outputs High-Impedance Space-Saving SSOP Package Eliminates Inductors/Transformers, Simplifies EMI Compatibility Issues Low-Cost Alternatives to Optically Isolated Transceivers with Supply Voltages as Low as 3.0V Still meet the EIA/TIA-232 standard
