Quad RS-422/RS-485 receiver for low-voltage differential lines
35 mV hysteresis — noise margin on differential lines
The 35 mV receiver hysteresis provides a clean switching threshold on differential pairs, which is critical when the cable runs through a factory floor or alongside motor drives. This built-in margin reduces the risk of bit errors from coupled noise without requiring external filtering.
No last-time-buy or obsolescence risk is indicated.
