It supports data rates up to 235Kbps over the IrDA protocol, which is the typical ceiling for consumer and light-industrial infrared links — think handheld terminals, medical monitors, or POS peripherals that beam data across a desk rather than through a wall. ## 235Kbps data rate — what it means for the link Data rate is 235Kbps. ## Full-duplex operation Full duplex means the driver and receiver can run simultaneously, which is the normal IrDA mode for bidirectional packet exchange. No half-duplex turnaround delay to account for in the firmware timing. ## Lifecycle and sourcing Listed as Active and ROHS3 compliant.","metaTitle":"MAX3120CUA+ IrDA Transceiver, Full Duplex, 235Kbps, 8-uMAX","metaDescription":"MAX3120CUA+ IrDA transceiver, full duplex, 235Kbps data rate, 3V–5.5V supply, 8-uMAX package.
