The MC10ELT/100ELT21 is a differential PECL to TTL translator.
Because PECL (Positive ECL) levels are used, only +5 V and ground
are required. The small outline 8-lead package and the single gate of
the ELT21 makes it ideal for those applications where space,
performance and low power are at a premium.
The VBB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
The 100 Series contains temperature compensation.
