TIMING CHARACTERISTICS

(VDD = +2.7V to +6V, VPP = +40V to (VNN + 200V), VNN = -40V to -160V, TA = TMIN to TMAX, unless otherwise noted. Typical values

are at TA = +25°C.) (Note 2)

Note 2: Specifications at 0°C are guaranteed by correlation and design.

Note 3: The analog-signal input VCOM_ and VNO_ must satisfy VNN

≤ (VCOM_, VNO_) ≤ VPP, or remain unconnected during power-up

and power-down.

Note 4: Guaranteed by design and characterization; not production tested.
