NOT RECOMMENDED FOR NEW DESIGNS Micrel, Inc. TTL-to-DIFFERENTIAL ECL TRANSLATOR FEATURES ■ ■ ■ ■ ■ SY100ELT24 SY100ELT24 DESCRIPTION 500ps typical propagation delay Differential ECL output PNP TTL input for minimal loading Flow-through pinouts Available in 8-pin SOIC package The SY100ELT24 is a TTL-to-differential ECL translator. Because ECL levels are used, a +5V, –5.2V (or –4.5V) and ground are required. The small outline 8lead SOIC package and the single gate of the ELT24 makes it ideal for those applications where performance, space and low power are at a premium.
