The USC1080 is an 8-bit high speed parallel flash A/D converter. The device employs an internal Grey code structure to eliminate large output errors on fast slewing input signals. It is fully TTL compatible, requiring a +5V, 12V supply and a wide tolerance negative supply of -3V to -6V. Three-state TTL outputs allow direct drive of a data bus or common I/O memory.

The USC1080 contains 256 parallel comparators across a precision input reference network. The comparator outputs are fed to latches and then to an encoder network, to produce an 8-bit data byte plus an over-range bit. The data is latched and converted to 3-states LS-TTL outputs.

Applications include video display and radar processing, high speed instrumentation and TV broadcast encoding.
