description 3.0ns typical propagation delay <500ps typical output-to-output skew differential pecl inputs 24ma ttl outputs flow-through pinouts available in 8-pin soic package the sy10/100elt23 are dual differential pecl-to-ttl translators. because pecl (positive ecl) levels are used, only +5v and ground are required. the small outline 8-lead soic package and the low skew dual gate design of the elt23 makes it ideal for applications which require the translation of a clock and a data signal. the elt23 is available in both ecl standards: the 10elt is compatible with positive ecl 10h logic levels, while the 100elt is compatible with positive ecl 100k logic levels. features dual differential pecl-to-ttl translator pin names pin configuration/block diagram pin function q n ttl outputs d n differential pecl inputs v cc +5.0v supply gnd ground soic top view precision edge sy10elt23 sy100elt23 final 1 2 3 4 5 6 7 8 d 0 v cc q 0 gnd q 1 d 0 pecl ttl d 1 d 1 1 rev.: i amendment: 0 issue date: february 2003 precision edge is a trademark of micrel, inc. precision edge
