Description
Wiper Terminal W. GND ≤ V
Positive Power Supply. Specified for non-OTP operation from 2.7 V to 5.5 V. For OTP programming, V
must be set within the window of 5 V to 5.5 V for the 1 kΩ (DD8) and 10 kΩ (DD9) options, or within the
window of 4.75 V to 5.25 V for the 50 kΩ (DYG) and 100 kΩ (DYH) options, and be capable of sourcing 100 mA.
Common Ground.
Serial Clock Input. Requires a pull-up resistor. If it is driven directly from a logic controller without the pull-up
resistor, ensure that the V
