This octal ECL-to-TTL translator is designed to
provide a efficient translation between a 100K
ECL signal environment to a TTL signal
environment. This device is designed specifically
ECL/TTL

Two output-enable pins, OE1 and OE2 are
provided. These control inputs are ANDed
together with OE1 being ECL compatible and OE2
being TTL compatible. This offers the choice of
controlling the outputs of the device from either a
TTL or ECL signal environment.
