The MC10H125 is a quad translator for interfacing data and control signals

between the MECL section and saturated logic section of digital systems. The

10H part is a functional/pinout duplication of the standard MECL 10K family

part, with 100% improvement in propagation delay, and no increase in

power–supply current.

Outputs of unused translators will go to low state when their inputs are left

open.

APPLICATION INFORMATION

The MC10H125 incorporates differential inputs and

Schottky TTL “totem pole” outputs. Differential inputs

allow for use as an inverting/non–inverting translator or

as a differential line receiver . The V

reference voltage

is available on Pin 1 for use in single–ended input biasing.

The outputs of the MC10H125 go to a low–logic level

whenever the inputs are left floating, and a high–logic

output level is achieved with a minimum input level of 150

p–p

An advantage of this device is that MECL–level

information can be received, via balanced twisted pair

lines, in the TTL equipment. This isolates the MECL–logic

from the noisy TTL environment. Power supply

requirements are ground, +5.0 volts and –5.2 volts.
