PARAMETER MEASUREMENT INFORMATION
2.08V
Output Under Test
CL = 100 pF1
RL = 800Ω
NOTES:
1. CL includes probe and fixture capacitance.
The AC testing inputs are driven at 2.4V for logic high and 0.4V for logic low. Timing measurements are made
at 2V for logic high and 0.8V for logic low for both inputs and outputs.
