The SN65EL16 is a differential PECL/ECL receiver with PECL/ECL output. The device includes circuitry to hold Q to a low logic level when the inputs are in an open condition.
The VBB pin is a reference voltage output for the device. When the device is used in the single-ended mode, the unused input should be tied to VBB. This reference voltage can also be used to bias the input when it is ac coupled. When the VBB pin is used, place a 0.01-µF decoupling capacitor between VCC and VBB. Also, limit the sink/source current to <0.5 mA to VBB. Leave VBB open when it is not used.
The SN65EL11 is housed in an industry-standard SOIC-8 package and is also available in a TSSOP-8 package.
