5kV Isolated 20Mbps Half-Duplex PROFIBUS/
RS-485 Transceivers with ±35kV ESD Protection
DC Electrical Characteristics (continued)
(VDDA – VGNDA = 1.71V to 5.5V, VDDB – VGNDB = 4.5V to 5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are
at VDDA – VGNDA = 3.3V, VDDB – VGNDB = 5V, VGNDA = VGNDB, and TA = +25°C.) (Notes 2, 3)
