description

This octal ECL-to-TTL translator is designed to

provide efficient translation between a 10KH

signal environment and a TTL signal environment.

This device is designed specifically to improve the

performance and density of ECL-to-TTL CPU/bus

oriented functions such as memory address

drivers,

clock

drivers,

and

bus-

oriented receivers and transmitters while eliminat-

ing the need for three-state overlap protection.

Two output enables, OE1 and OE2, are provided.

These enable inputs are ANDed together with

OE1 being ECL-compatible and OE2 being

TTL-compatible. This offers the choice of controll-

ing the outputs of the device from either a TTL or

ECL signal environment.

The SN10KHT5538 is characterized for operation

from 0

°C to 75°C.
