100325 Low Power Hex ECL-to-TTL Translator

100325
Low Power Hex ECL-to-TTL Translator

General Description

The 100325 is a he x translato r for convert ing F100K logic
levels to TTL logic levels. Differential inputs a llow each cir­cuit to be used as an inverting, no n-inverting or differential
receiver. An internal reference voltage generator p rovides
V

BB

for single-ended operation, or for use in Schmitt trigger

applications. All inputs have 50k

Ω pull-down resistors.

When the inputs are either un connected or at the same
potential the outputs will go LOW.

When used in sin gle-ended operation the apparent input
threshold of the true inputs is 20mV to 40mV higher (posi­tive) than the threshold of the com plementary inputs. The
V

EE

and V

TTL

power may be applied in either order.

Features

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: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: 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.

Note 4: Test one output at a time.
