Quad Differential Receiver

The MC100LVEL17 is a 3.3 V ECL, quad differential receiver. The device is functionally equivalent to the E116 device with the capability of operation from either a -3.3 V or +3.3 V supply voltage.

Under open input conditions, the Dbar input will be biased at VCC /2 and the D input will be pulled down to VEE . This operation will force the Q output LOW and ensure stability.

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.
