100393 Low Power 9-Bit ECL-to-TTL Translator with Latches
100393
Low Power 9-Bit ECL-to-TTL Translator with Latches
General Description
The 100393 is a 9-bit translator for converting F100K logic
levels to TTL logic levels. A LOW on the latch enable (LE)
latches the data at the input state. A HIGH on the LE
makes the latches transparent. A HIGH on either the ECL
or TTL output enable (OE
ECL or OE TTL), holds the out-
puts in a high impedance state.
The 100393 is designed with TTL, 64 mA outputs for Bus
Driving capability. All ECL inputs have 50 k pull-down
resistors. When the inputs are either unconnected or at the
same potential, the outputs will go LOW.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The Recommended Operating Conditions table will define the conditions
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 worst case values normally occur at the temperature extremes,
additional noise immunity and guard banding 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.
