description
This octal TTL-to-ECL translator is designed to
provide efficient translation between a TTL signal
environment and a 100K ECL signal environment.
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 SN100KT5578 is characterized for operation
from 0°C to 85°C.
