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, noninverting, or differential receiver. An internal reference generator 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 Interfacing.
Features
■Operates from a single + 5V supply
■3-STATE outputs
■2000V ESD protection
■VBB supplied for single-ended operation

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: Either voltage limit or current limit is sufficient to protect inputs.
