Description

The MC100ELT21 is a differential PECL to TTL translator. Because PECL (Positive ECL) levels are used only +5V and ground are required. The small outline 8-lead SOIC package and the single gate of the ELT21 makes it ideal for those applications where space, performance and low power are at a premium. Because the mature MOSAIC 1.5 process is used, low cost can be added to the list of features.

The V_BB output allows the MC100ELT21 to also be used in a single-ended input mode. In this mode the VBB output is tied to the IN input for a non-inverting buffer or the IN input for an inverting buffer. If used the V_BB pin should be bypassed to ground via a 0.01mF capacitor.

The MC100ELT21 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.
