DESCRIPTION


The AZ100ELT23 is a dual differential PECL to CMOS/TTL translator. Because PECL (Positive ECL) levels
are used, only V
CC
and ground are required. The small outline 8-lead packaging and the low skew, dual gate design
of the ELT23 makes it ideal for applications that require the translation of a clock and a data signal.
The ELT23 is available in only the ECL 100K standard. Since there are no PECL outputs or an external V
BB

reference, the ELT23 does not require both ECL standard versions. The PECL inputs are differential; there is no
specified difference between the differential input 10K and 100K standards. Therefore the AZ100ELT23 can accept
any standard differential PECL input referenced from a V
CC
of 3.0V to 5.5V.
NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
