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 V
pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to V
as a switching reference voltage. V
may also rebias AC coupled inputs. When used, decouple V
and V
via a 0.01 F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, V
should be left open.
The 100 Series contains temperature compensation.
