DESCRIPTION

The SN65ELT23 is a low power dual PECL-to-TTL

translator device. The device includes circuitry to

maintain a known logic low level when inputs are in

an open condition. The SN65ELT23 is housed in an

industry standard SOIC-8 package and is also

available in an optional TSSOP-8 package.
