100390
Low Power Single Supply Hex PECL-to-TTL Translator
General Description
The 100390 is a hex translator for converting F100K logic
levels to TTL logic levels. Unlike other level translators, the
100390 operates using only one +5V supply. Differential
inputs allow each circuit to be used as an inverting, nonin-
verting, or differential receiver. An internal reference gener-
ator provides VBB for single-ended operation. The standard
FAST 3-STATE outputs are enabled by a common active
low TTL compatible OE input. Partitioned VCCs on chip are
brought out on separate power pins, allowing the noisy TTL
VCC power plane to be isolated from the relatively quiet
ECL VCC. The 100390 is ideal for applications limited to a
single +5V supply, allowing for easy ECL to TTL Interfac-
ing.
