Manufacturer Part Number
MC10319P
Description
7V high speed 8-bit analog-to-digital flash converter
Manufacturer
Motorola
Datasheet
High Speed 8-Bit
Analog-to-Digital Converter
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.
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.
