100391

Low Power Single Supply Hex TTL-to-PECL Translator

General Description

The 100391 is a hex translator for converting TTL logic lev-

els to F100K PECL logic levels. The unique feature of this

translator, is the ability to do this translation using only one

+5V supply. The differential outputs allow each circuit to be

used as an inverting/non-inverting translator, or as a differ-

ential line driver. A common enable (E), when LOW, holds

all inverting outputs HIGH and all non-inverting inputs

LOW.

The 100391 is ideal for those mixed PECL/TTL applica-

tions which only have +5V supply available. When used in

the differential mode, the 100391, due to its high common

mode rejection, overcomes voltage gradients between the

TTL and PECL ground systems.

Features

s Operates from a single +5V supply

s Differential PECL outputs

s 2000V ESD protection

s Companion chip to 100390 hex PECL-to-TTL translator
