description

These octal TTL-to-ECL translators are designed to provide efficient translation between a TTL signal environment and a 10KH ECL signal environment. The designer has a choice of inverting ('5542) or true ('5543) outputs. Two pins, and , are provided for output enable control. These control inputs are negative ANDed together, with being ECL compatible and being TTL compatible. This offers the choice of controlling the outputs of the devices from either a TTL or ECL signal environment. The outputs, when disabled, go to a normal ECL logic low level.

The SN10KHT5542 and SN10KHT5543 are characterized for operation from 0^o C to 75^oC.
