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 VCC ≥ 3 V in PECL mode, or VEE ≤ 3 V in NECL mode. The device is housed in an industry-standard SOIC-8 package and is also available in TSSOP-8 package option.
