The MC10ELT/100ELT21 is a differential signal converter that is used to convert PECL signals and TTL signals
The document describes the MC10ELT/100ELT21 series as a differential PECL to TTL translator designed for applications requiring space efficiency, performance, and low power. It utilizes the MOSAIC 1.5 process and is available in an 8-lead SOIC package.
The device supports both MECL 10H and ECL 100K logic standards depending on the specific model (MC10ELT or MC100ELT). It features a Vpp output that allows for single-ended input mode operation, functioning as either a non-inverting or inverting buffer when configured appropriately.
| Typical Propagation Delay | 3.5ns |
|---|---|
| Power Supply Current (TTL Output) | 24mA |
| Package Type | Small Outline SOIC Package |
| Operating Temperature Range | -40 to 85 °C |
The ELT21 is available in both ECL standards: the 10ELT is compatible with positive MECL 10H logic levels while the 100ELT is compatible with positive ECL 100K logic levels.
The Vpp output allows this by tying the VBB output to the IN input for a non-inverting buffer or to the IN input for an inverting buffer.
