DESCRIPTION  
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  
low logic level when inputs are in an open condition  
or < 1.3 V.

VBB  
Positive supply  
The VBB pin is a reference voltage output for the  
device. When the device is used in 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 it is used, place a  
Negative supply  
Reference voltage output  
0.01µF 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 SN65ELT21 is housed in an industry standard  
SOIC-8 package and is also available in an optional  
TSSOP-8 package.
