MAX14780E:+5.0V, ±30kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 Transceiver

RS-485 Transceiver with High ±30kV ESD Protection for Robust System Performance

The MAX14780E is a +5V, ±30kV HBM ESD half duplex RS-485/422 transceiver. The MAX14780E features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps. The MAX14780E is available in an 8-pin SO and PDIP packages operating over a temperature range from -40°C to +85°C.
