Micrel, Inc. SY100ELT25 DIFFERENTIAL SY100ELT25 ECL-to-TTL TRANSLATOR FEATURES DESCRIPTION 2.6ns typical propagation delay The SY100ELT25 is a differential ECL-to-TTL translator. Because ECL levels are used, a +5V, 5.2V Differential ECL inputs (or 4.5V) and ground are required. The small outline 8- 24mA TTL outputs lead SOIC package and the single gate of the ELT25 Flow-through pinouts makes it ideal for those applications where performance, Available in 8-pin SOIC package space and low power are at a premium. The VBB output allows the ELT25 to also be used in a single-ended input mode. In this mode the VBB output is tied to the D input for a non-inverting buffer or the D input for an inverting buffer. If used the VBB pin should be bypassed to ground via a 0.01 F capacitor.
