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

pin is a reference voltage output for the

Q, Q PECL/ECL outputs

device. When the device is used in the single-ended

Positive supply

mode, the unused input should be tied to V

. This

Negative supply

reference voltage can also be used to bias the input

Reference voltage output

when it is ac coupled. When the V

pin is used,

place a 0.01- µ F decoupling capacitor between V

and V

. Also, limit the sink/source current to < 0.5

mA to V

. Leave V

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.

(1) The device meets the specifications after thermal balance has been established when mounted in a socket or printed-circuit board with

maintained transverse airflow greater than 500 lfpm (2.54 m/s). Electrical parameters are assured only over the declared operating

temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are

applied individually under normal operating conditions and are not valid simultaneously.
