DESCRIPTION
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 V_BB 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 V_BB. This
reference voltage can also be used to bias the input
when it is ac coupled. When the V_BB pin is used,
place a 0.01-µF decoupling capacitor between V_CC
and V_BB. Also, limit the sink/source current to <0.5
mA to V_BB. Leave V_BB 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.
