Differential Receiver

The MC100LVEL16 is a differential receiver. The device is functionally equivalent to the EL16 device, operating from a 3.3 V supply. The LVEL16 exhibits a wider VIHCMR range than its EL16 counterpart. With output transition times and propagation delays comparable to the EL16 the LVEL16 is ideally suited for interfacing with high frequency sources at 3.3 V supplies. Under open input conditions, the Q input will be pulled down to VEE and the Qbar input will be biased to VCC/2. This condition will force the Q output low. 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.
