DESCRIPTION

The SY100S391 is a hex TTL-to-PECL translator for converting TTL logic levels to 100K 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.

FEATURES

■ Operates from a single +5V supply

■ Differential PECL outputs

■ Function and pinout compatible with Fairchild F100K

■ Available in 28-pin PLCC packages
