PROGRAMMABLE IMPEDANCE OUTPUT BUFFER OPERATION
Refer to Functional Operation section for more detailed explanation.
DC OUTPUT BUFFER CHARACTERISTICS – PROGRAMMABLE IMPEDANCE PUSH–PULL OUTPUT BUFFER MODE

NOTES:
1. IOL = (VDDQ/2)/(RQ/5) for values of RQ = 175 Ω ≤ RQ ≤ 350 Ω.
2. | IOH | = (VDDQ/2)/(RQ/5) for values of RQ = 175 Ω ≤ RQ ≤ 350 Ω.
3. IOL ≤ 100 µA.
4. | IOH | ≤ 100 µA.
5. The impedance controlled mode is expected to be used in point–to–point applications, driving high impedance inputs.
6. The ZQ pin is connected through RQ to VSS for the controlled impedance mode.

NOTES:
1. IOL ≤ 8 mA
2. | IOH |≤ 8 mA
3. IOL ≤ 100 µA
4. | IOH |≤ 100 µA
5. The push–pull output mode is expected to be used in bussed applications and may be series or parallel terminated. Conforms to the JEDEC
Standard JESD8–6 Class 1.
6. The ZQ pin is connected to VDD to enable the minimum impedance mode.
