Note 1: “Absolute Maximum Ratings” are these beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should
be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 2: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified.
Note 3: All typicals are given for V
CC
= +3.3V and T

= +25˚C, unless otherwise stated.
Note 4: ESD Rating: HBM (1.5 kΩ, 100 pF)

Note 5: CL includes probe and fixture capacitance.
Note 6: Generator waveforms for all tests unless otherwise specified: f = 1MHz, ZO = 50Ω,t

).
Note 7: The DS92LV222A is a current mode device and only functions datasheet specifications when a resistive load is applied to the drivers outputs.
Note 8: During receiver select transition(s), data must be held in a steady state 15 ns before and 15 ns after the RSEL pin changes state.
Note 9: Channel-to-channel skew is the measurement between outputs of D0 and D1.
