General Description
The 100391 is a hex translator for converting TTL logic levels 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 differential 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 applications 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
■ Operates from a single +5V supply
■ Differential PECL outputs
■ 2000V ESD protection
■ Companion chip to 100390 hex PECL-to-TTL translator
