MC100ELT21D.

The MC10ELT/100ELT21 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 ELT21 to also be used in a single-ended input mode.  In this mode the V_BB  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 0.01F capacitor.

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.
