Overview



5V TTL-to-Differential PECL Translator   Datasheet
The SN65ELT20 is a TTL-to-differential PECL translator. It operates on a 5V supply and ground only. The output is undetermined when the inputs are left floating. The low output skew makes the device an ideal solution for clock or data signal translation. The SN65ELT20 is housed in an industry-standard SOIC-8 package and is also available in a TSSOP-8 package.

5V Dual TTL-to-Differential PECL Translator    Datasheet
The SN65ELT22 is a dual TTL-to-differential PECL translator. It operates on +5V supply and ground only. The output is undetermined when the inputs are left floating. The low output skew makes the device an ideal solution for clock or data signal translation. It is housed in an industry standard SOIC-8 package and is also available in an optional TSSOP-8 package.

3.3V Dual LVTTL/LVCMOS-to-Differential LVPECL Buffer   Datasheet
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. It is housed in an industry standard SOIC-8 package and is also available in TSSOP-8 package option.

3.3V Dual LVTTL-to-Differential LVPECL Translator   Datasheet
The SN65LVELT22 is a dual LVTTL-to-differential LVPECL translator buffer. It operates on +3V supply and ground only. The output is driven default high when the inputs are left floating or unused. The low output skew makes the device the ideal solution for clock or data signal translation. The SN65LVELT22 is housed in an industry standard SOIC-8 package and is also available in TSSOP-8 package option.
