ODT Timing for Precharge Power‐Down Mode
Note: Both ODT to Power Down Endtry and Exit Latencies tANPD and tAXPD are not met, therefore Power‐Down Mode timings have to be applied.

Both ODT to Power Down Entry and Exit Latency timing parameter tANPD and tAXPD are met, therefore Non‐Power Down Mode timings have to be applied.
ODT turn‐on time, tAON(Min) is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max, tAON(Max) is when the
ODT resistance is fully on. Both are measured from tAOND.
ODT turn off time min, tAOF(Min), is when the device starts to turn off the ODT resistance. ODT turn off time max, tAOF(Max) is when the bus is in high
impedance. Both are measured from tAOFD.
