Operating from a 4.75 V to 5.25 V supply, the device includes one driver and one receiver with 25 mV of receiver hysteresis for noise immunity on long bus runs. ## Data rate and bus topology constraints At 250 kbps, the MAX3158EPI is suited for fieldbus links, sensor networks, and PLC-to-I/O communication where cable lengths exceed 100 m. The integrated isolation eliminates the need for external optocouplers or isolated DC-DC modules on the bus side, reducing BOM count and board area. Full-duplex mode allows simultaneous transmit and receive on a four-wire bus; half-duplex mode uses a two-wire bus with driver enable control. The 25 mV hysteresis ensures reliable edge detection in noisy industrial environments. ## Active production and sourcing posture The part is RoHS non-compliant (lead-bearing termination), which may restrict use in EU RoHS-exempt applications or require a waiver for new designs. The 28-PDIP package is a standard through-hole footprint, compatible with socketed or soldered assembly.","metaTitle":"MAX3158EPI RS-485 Transceiver with Isolation - Analog","metaDescription":"MAX3158EPI RS-485/RS-422 transceiver with integrated isolation, 250 kbps, full/half duplex, -40°C to 85°C, 28-PDIP.
