9 Electrical Characteristics and Requirements
The following electrical characteristics are preliminary and are subject to change. Electrical characteristics refer to
the behavior of the device under specified conditions. Electrical requirements refer to conditions imposed on the
user for proper operation of the device. The parameters below are valid for the conditions described in Section 8.3,
Recommended Operating Conditions.

Note 1. The small-signal buffer must be used in single-ended mode where an ac waveform (sine or square) is applied to CKI and a dc voltage
Note 2. Duty cycle for a sine wave is defined as the percentage of time during each clock cycle that the voltage on CKI exceeds the voltage on
