Dual Differential LVPECL to
TTL Translator
The MC100LVELT23 is a dual differential LVPECL to TTL translator.
Because L VPECL (Positive ECL) levels are used only +3.3V and ground
are required. The small outline 8-lead SOIC package and the dual gate
design of the LVELT23 makes it ideal for applications which require the
translation of a clock and a data signal.
The LVELT23 is available in only the ECL 100K standard. Since there
are no L VPECL outputs or an external VBB reference, the L VELT23 does
not require both ECL standard versions. The LVPECL inputs are
differential; there is no specified difference between the differential input
10H and 100K standards. Therefore, the MC100L VEL T23 can accept any
standard differential LVPECL input referenced from a VCC of 3.3V.

Note:
1) Pulling the output higher than VCC is not recommended. Doing so
causes excessive leakage and possible latchup leading to reliability
risk.
