PECL/ECL 1:2 Fanout Buffer
SN65LVEP11
The SN65LVEP11 is a differential 1:2 PECL/ECL fanout buffer. The device includes
circuitry to maintain known logic levels when the inputs are in an open condition.
Single-ended clock input operation is limited to V

≤3Vin
NECL mode. The device is housed in an industry-standard SOIC-8 package and is also
available in a TSSOP-8 package option.
