The device can tolerate this range of voltages w.r.t. V
operation of the differential input circuitry is only guaranteed when the other specifications in this table are met.
With 100 Ω load across the differential outputs.
The differential outputs can easily be interfaced to LVDS, LVPECL, and CML inputs on neighboring ICs using a few external
passive components. See
