It handles signaling up to 250 kbps.
The receiver includes 70 mV of hysteresis, which helps reject noise on long cable runs common in RS485 installations.
Housed in a 10-lead uMAX/uSOP package (3.00 mm width, 0.118" pitch), this is a compact surface-mount part suited for dense PCBs.
It is ROHS3 compliant. No stock or lead-time figures are published here; submit an RFQ for a real-time quote.
No, they are not equivalent. The MAX1481CUB+ is a 5 V full-duplex transceiver at 250 kbps, while the MAX3485 family typically operates at 3.3 V and offers data rates from 250 kbps up to 12 Mbps depending on the suffix. Pin compatibility varies by package variant; always check the respective datasheets before substituting.
The maximum data rate is 250 kbps. This is sufficient for most RS485 fieldbus applications at standard baud rates (9600, 19200, 115200) but not for high-speed protocols like Profibus at 12 Mbps.
