MAXM22511 Datasheet | Maxim Integrated

Description The MAXM22510 and MAXM22511 isolated RS-485/ RS-422, full-duplex, transceiver modules provide 2500VRMS (60s) of galvanic isolation between the cableside (RS-485/RS-422 driver/receiver side) and the UARTside of the device. An integrated DC-DC powers the cable-side of the module. No external ponents are required. Isolation improves munication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust munication up to 500kbps (MAXM22510) and 25Mbps (MAXM22511). The MAXM22510/MAXM22511 operate from a single 3.3V supply on the UART-side. An integrated DC-DC converter generates the 3.3V operating voltage for the cable-side of the module. The devices include one drive channel and one receive channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a mon bus. Integrated true fail-safe circuitry ensures a logic-high on the receiver output when inputs are shorted or open. Undervoltage lockout disables the driver when cable-side or UART-side power supplies are below functional levels. The driver outputs and receiver inputs are protected from ±35k V electrostatic discharge (ESD) to GNDB on the cable-side, as specified by the Human Body Model (HBM). The MAXM22510/MAXM22511 are available in an LGA 44-pin package and operate over the -40°C to +105°C temperature range. Ordering Information appears at end of data sheet.
