SNOSAL5A – SEPTEMBER 2005 – REVISED MARCH 2013

16V Electrical Characteristics

(1)

Unless otherwise specified, all limits ensured for TJ = 25°C, VDD = 16V, VSS = 0V, & CLOAD = 100 pF (Gamma & VCOM Buffers).

Boldface limits apply at the temperature extremes.

(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing condition result in very

limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical table under

conditions of internal self-heating where TJ > TA.

(2)

All limits are specified by design or statistical analysis.

(3)

Typical values represent the parametric norm at the time of characterization.

(4)

Slew Rate is measured for VIN = 4 VPP. 10% -90% values are used. Slew rate is the average of the rising and falling slew rates

(5)

4 VPP pulse (50 ns rise time) applied to one side of 100 pF series output capacitance, other side connected to output of buffer. Output to

within 0.1% of input voltage.
