NOT RECOMMENDED FOR NEW DESIGNS LOW-POWER HEX TTL-TO-PECL TRANSLATOR Micrel, Inc. FEATURES ■ ■ ■ ■ SY100S391 SY100S391 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. The SY100S391 is ideal for those mixed PECL/TTL applications which only have a +5V supply available. When used in the differential mode, the S391, due to its high common mode rejection, overcomes voltage gradients between the TTL and PECL ground systems. Operates from a single +5V supply Differential PECL outputs Function and pinout compatible with Fairchild F100K Available in 28-pin PLCC packages BLOCK DIAGRAM E D0 Q0 Q0 D1 Q1 Q1 D0 — D5 Data Inputs (TTL) D2 Q2 Q2 Q0 — Q5 Data Outputs (PECL) Q0 — Q5 Inverting Data Outputs (PECL) Q3 Q3 E Enable Input (TTL) D3 VCCA VCCO for ECL Outputs D4 Q4 Q4 D5 Q5 Q5 M9999-042307 hbwhelp@micrel.com or (408) 955-1690 PIN NAMES Pin Function Rev.: I 1 Amendment: /0 Issue Date: April 2007 SY100S391 Micrel, Inc.

The specified limits represent the "worst case" value for the parameter. Since these values normally occur at the temperature extremes, additional noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under "worst case" conditions.
