DATA & CLK Signals

(1)

All voltages are with respect to the potential at the GND pin.

(2)

All limits specified at room temperature and at temperature extremes. All room temperature limits are production tested, specified

through statistical analysis or by design. All limits at temperature extremes are specified via correlation using standard Statistical Quality

Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(3)

Ω to 20 kΩ
