Notes
15.The common mode range defines the allowable range of INPUT+ and INPUT- when INPUT+ =
16.Maximum ICC is measured with VCC = MAX, RFENx = 0,TA = 25°C, with all channels and Serial Line Drivers enabled, sending a continuous alternating 01 pattern, and outputs unloaded.
17.Typical ICC is measured under similar conditions except with VCC = 3.3V, TA = 25°C, RFENx = 0, with all channels enabled and one Serial Line Driver per transmit channel sending a continuous alternating 01 pattern. The redundant outputs on each channel are powered down and the parallel outputs are unloaded.
18.Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
19.The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.
