Notes
12. The common mode range defines the allowable range of INPUT+ and INPUTwhen INPUT+ = INPUT. This marks the zero-crossing between the true and
complement inputs as the signal switches between a logic-1 and a logic-0.
13. Maximum I_CC is measured with V_CC = MAX, RFENx = 0, T_A = 25°C, with all channels and Serial Line Drivers enabled, sending a continuous alternating 01
pattern, and outputs unloaded.
14. Typical I_CC is measured under similar conditions except with V_CC = 3.3V, T_A = 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.
15. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
16. The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.
