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, OE1 and OE2, are provided for output

enable control. These control inputs are negative

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

outputs, when disabled, go to a normal ECL logic

low level.

The SN10KHT5542 and SN10KHT5543 are

characterized for operation from 0°C to 75°C.
