100391 Low Power Single Supply Hex TTL-to-PECL Translator
100391
Low Power Single Supply Hex TTL-to-PECL Translator
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-i nvert ing tr anslator, or as a differential line driver. A common enable (E), whe n LOW, holds
all inverting outputs HIGH and all non-inverting inputs
LOW.
The 100391 is ideal fo r those mixed PECL/TTL applications which only have
+5V supply available . When use d in
the differential mode, the 10 0391, due to its hi gh common
mode rejection, overco mes voltag e gradients be tween 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

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: The “Absolute Maximum Ratings” are those value s beyond which
the safety of the dev ice cannot b e guaranteed . The device sh ould not be
operated at these limit s. The parametric values defi ned in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recomm ended O peratin g Cond itions ” table will defin e the condition s
for actual device operation.
Note 2: Either voltage lim it or c urrent limit is sufficient to pro te c t in puts.
Note 3: ESD testing conforms to MIL-STD-883, Method 3015.

Note 4: 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 decreasin g the al l owable syste m opera ti ng ran ge s. Cond it i ons fo r t estin g sho w n in the tabl es are chosen to guarantee operation under “worst case” conditions.
