3 Description

The SN65EPT22 is a low power dual LVTTL to

LVPECL translator device. The device includes circuitry to maintain known logic HIGH level when

inputs are in open condition. The SN65EPT22 is

housed in an industry standard SOIC-8 package and

is also available in TSSOP-8 package option.
