(VDDA – VGNDA = 1.71V to 5.5V, VDDB – VGNDB = 4.75V to 5.25V, 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 1, 2)

Note 1: All devices are 100% production tested at TA = +85°C. Specifications over temperature are guaranteed by design.

Note 2: All currents into the device are positive. All currents out of the device are negative. All voltages are referenced to their

respective ground (GNDA or GNDB), unless otherwise noted.

Note 3: This is the differential voltage from A to B that the driving device must see on the bus to disable its driver.

Note 4: Not production tested. Guaranteed by design.

Note 5: CMTI is the maximum sustainable common-mode voltage slew rate while maintaining the correct output states. CMTI

applies to both rising and falling common-mode voltage edges. Tested with the transient generator connected between

GNDA and GNDB. VCM = 1kV
