MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC44251/D Advance Information Triple 8-Bit Video ADC Three-State Outputs CMOS The MC44251 contains three independent parallel analog to digital flash converters (ADC).

Each ADC consists of 256 latching comparators and an encoder.

Video may be ac or dc coupled.

With ac coupling, input clamping provides for internal dc restoration.

The MC44251 also contains a dithering generator for video processing performance enhance

MC44251 Features

* waveform for proper operation. Yin , U in, and Vin may be used instead of the RGB signals. In this case the conversion will be a YUV analog

* to

* digital conversion. Ibias (Pin 33) The comparator bias current is set by connecting an external resistor between Ibias and ground. The conv
