description
This octal ECL-to-TTL translator is designed to provide efficient translation between a 100K 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 eliminating the need for three-state overlap protection. Two pins OE1 and OE2 are provided for output-enable control. 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. The SN100KT5539 is characterized for operation from 0°C to 85°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The TTL input voltage ratings may be exceeded provided the input current ratings are observed.
