1. In “Normal” mode (MS=0). Measured with respect to REF output. The minimum delay time is zero

(or less, by 1.5 ns typically)

2. In PWM mode (MS=1). The minimum output pulse width for reliable operation is 5 ns; programmed

values less than this may produce reduced output voltage levels or no output at all.

3. This is the deviation from a straight line drawn between the step zero value and the maximum

programmed delay time.
