NOTES:

1. The parameters listed in Table 3 are controlled via design or process parameters. Min and Max Limits are guaranteed but not directly

tested. These parameters are characterized upon initial design release and upon design changes which affect these characteristics.

NOTES:

1. All voltages referenced to device GND.

2. AC measurements assume RL = 500

Ω, CL = 50pF, Input TR = TF = 3ns, VIL = GND, VIH = 3V.

3. For functional tests VO

≥ 4.0V is recognized as a logic “1”, and VO ≤ 0.5V is recognized as a logic “0”.
