description
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 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. 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. The SN100KT5541 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.
