NOTES:

3. All voltages referenced to device GND.

4. AC measurements assume RL = 500Ω, CL = 50pF, Input TR = TF = 3ns, VIL = GND, VIH = VCC.

Limits are guaranteed but not directly tested. These parameters are characterized upon

initial design release and upon design changes which affect these characteristics.

NOTES:

5. All voltages referenced to device GND.

6. AC measurements assume RL = 500Ω, CL = 50pF, Input TR = TF = 3ns, VIL = GND, VIH = VCC.

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