Table 1. Pin Descriptions
The
SN65ELT21
is
a
differential
PECL-to-TTL
translator. It operates on +5-V supply and ground

only. The device includes circuitry to maintain Q to a

PECL data inputs
low logic level when inputs are in an open condition

TTL output
or < 1.3 V.
VCC
Positive supply
The VBB pin is a reference voltage output for the
VEE
Negative supply
device. When the device is used in single-ended
VBB
Reference voltage output
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 it is used, place a
0.01
F decoupling capacitor between V
CC and VBB.
Also limit the sink/source current to < 0.5 mA to VBB.
Leave VBB open when it is not used.
The SN65ELT21 is housed in an industry standard
SOIC-8 package and is also available in an optional
TSSOP-8 package.
