Internal ESD protection circuits protect the transceiver against electrostatic discharges (ESD) according to IEC 61000-4-2 of up to ±12 kV, and against electrical fast transients (EFT) according to IEC 61000-4-4 of up to
±4 kV.
The SN65HVD7x half-duplex family provides internal biasing of the receiver input thresholds in combination with large input threshold hysteresis. At a positive input threshold of VIT+ = –20 mV and an input hysteresis of
VHYS = 50 mV, the receiver output remains logic high under a bus-idle or bus-short condition even in the presence of 140-mVPP differential noise without the need for external failsafe biasing resistors.
Device operation is specified over a wide ambient temperature range from –40°C to 125°C.
