TTL-to-DIFFERENTIAL
ECLTRANSLATOR
SY100ELT24
FINAL
FEATURES
DESCRIPTION
■ 500ps typical propagation delay
■ Differential ECL output
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 8-
lead 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.
■ PNP TTL input for minimal loading
■ Flow-through pinouts
■ Available in 8-pin SOIC package
