AC Test Loads and Waveforms
Notes:
14. 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.
15. Maximum I
is measured with V
CC
=
MAX, RFEN
=
LOW, TA
=
25
°
C, with all Serial Line Drivers enabled, sending a constant alternating 01 pattern, and
outputs unloaded.
16. Typical I
is measured under similar conditions except with V
CC
=
3.3V, TA
=
25
°
C, RFEN
=
LOW, with one Serial Line Driver sending a continuous
alternating 01 pattern and parallel outputs unloaded.
17. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.
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 the point where the signal edges crosses this threshold voltage.
