The SN65EL16 is a differential PECL/ECL receiver
Table 1. Pin Description
with PECL/ECL output. The device includes circuitry
to hold Q to a low logic level when the inputs are in
PIN FUNCTION
an open condition.
D, D PECL/ECL data inputs
The V
BB
pin is a reference voltage output for the
Q, Q PECL/ECL outputs
device. When the device is used in the single-ended
V
CC
Positive supply
mode, the unused input should be tied to V
BB
. This
V
EE
Negative supply
reference voltage can also be used to bias the input
V
BB
Reference voltage output
when it is ac coupled. When the V
BB
pin is used,
place a 0.01- µ F 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.
