Notes
9. 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.
10. Maximum I
CC
is measured with V
CC
= MAX, T
A
= 25°C, with all channels and Serial Line Drivers enabled, sending a continuous alternating 01 pattern, and
outputs unloaded.
11. Typical I
CC
is measured under similar conditions except with V
CC
= 3.3V, T
A
= 25°C, with all channels enabled and one Serial Line Driver for each transmit
channel sending a continuous alternating 01 pattern. The redundant outputs on each channel are powered down and the parallel outputs are unloaded.
12. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
13. The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.
