description
This octal TTL-to-ECL translator is designed to
provide efficient translation between a TTL signal
environment and a 10KH ECL signal environ-
ment. This device is designed specifically to
improve the performance and density of
TTL-to-ECL CPU/bus-oriented functions such as
memory address drivers, clock drivers, and
bus-oriented receivers and transmitters.

The eight flip-flops of the ’5578 are edge-triggered D-type flip-flops. On the positive transition of the clock, the
Q outputs are set to the logic levels that were set up at the D inputs.
The output-control input OE does not affect the internal operations of the flip-flops. Old data can be retained
or new data can be entered while the outputs are off.
The SN10KHT5578 is characterized for operation from 0°C to 75°C.
