MOTOROLA ANALOG IC DEVICE DATA

High Speed 8-Bit

Analog-to-Digital Converter

The MC10319 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

+ 5.0 V supply and a wide tolerance negative supply of – 3.0 to – 6.0 V.

Three–state TTL outputs allow direct drive of a data bus or common I/O

memory.

The MC10319 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 overrange bit. The

data is latched and converted to 3–state LS–TTL outputs. The overrange bit

is always active to allow for either sensing of the overrange condition or ease

of interconnecting a pair of devices to produce a 9–bit A/D converter.

Applications include video display and radar processing, high speed

instrumentation and TV broadcast encoding.
