Notes:
9. All Voltage referenced to Ground.
10. Output are impedance controlled. Ioh=-(Vddq/2)/(RQ/5) for values of 175 ohms <= RQ <= 350 ohms.
11. Output are impedance controlled. Iol=(Vddq/2)/(RQ/5) for values of 175 ohms <= RQ <= 350 ohms.
12. Overshoot: V
IH (AC) < V DDQ +0.85V (Pulse width less than t CYC /2), Undershoot: V IL (AC) > -1.5V (Pulse width less than t CYC /2).
13. This spec is for all inputs except C and C clocks. For C and C clocks, V IL (Max.) = V
REF
– 0.2V.
14. Power-up: Assumes a linear ramp from 0v to V DD (min.) within 200ms. During this time V IH < V DD and V DDQ < V DD
