3.3 V ECL ÷·4 Divider

The MC100LVEL33 is an integrated div by 4 divider. The LVEL is functionally equivalent to the EL33 and works from a 3.3 V supply.

The reset pin is asynchronous and is asserted on the rising edge. Upon power-up, the internal flip-flops will attain a random state; the reset allows for the synchronization of multiple LVEL33's in a system.

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 F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.
