SEMICONDUCTOR TECHNICAL DATA The MC10ELT/100ELT26 is a 1:2 fanout 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 1:2 fanout design of the ELT23 makes it ideal for applications which require the low skew duplication of a signal in a tightly packed PC board. Because the mature MOSAIC 1.5 process is used, low cost can be added to the list of features. The VBB output allows the ELT26 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 VBB pin should be bypassed to ground via a 0.01µF capacitor. The ELT26 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. • • • • • • 8 1 D SUFFIX PLASTIC SOIC PACKAGE CASE 751-05 3.5ns Typical Propagation Delay <500ps Typical Output to Output Skew Differential PECL Inputs Small Outline SOIC Package 24mA TTL Outputs Flow Through Pinouts LOGIC DIAGRAM AND PINOUT ASSIGNMENT PIN DESCRIPTION NC 1 8 VCC 2 7 Q0 6 Q1 5 GND D TTL D 3 VBB 4 PECL PIN FUNCTION Qn D VCC VBB GND TTL Outputs Diff PECL Input +5.0V Supply Reference Output Ground This document contains information on a product under development.
