It integrates one driver and one receiver in a 28-SSOP surface-mount package, operating from a 4.75 V to 5.25 V supply over the 0 °C to 70 °C commercial temperature range. The receiver includes 25 mV of hysteresis for noise immunity on long cable runs. Typical applications include industrial control networks, building automation, and instrumentation where a balanced differential serial link is required. ## Sourcing and lifecycle — active production, no LTB risk The MAX3157CAI+ carries an Active product status with ROHS3 compliance. There is no last-time-buy or obsolescence notice, so it remains suitable for both new designs and ongoing production.","metaTitle":"MAX3157CAI+ RS-422/RS-485 Transceiver, 250kbps, 28-SSOP","metaDescription":"MAX3157CAI+ RS-422/RS-485 full-duplex transceiver, 250kbps data rate, 4.75-5.25V supply, 0-70°C.
