DESCRIPTION  
The AZ100ELT21 is a differential PECL to CMOS/TTL translator. Because PECL (Positive ECL) levels are  
used, only VCC and ground are required. The small outline 8-lead packaging and the single gate of the ELT21 makes  
it ideal for those applications where space, performance and low power are at a premium.  
The ELT21 provides a VBB output for single-ended use or a DC bias reference for AC coupling to the device.  
For single-ended input applications, the VBB reference should be connected to one side of the D0/D¯¯0 differential  
input pair. The input signal is then fed to the other D0/D¯¯0 input. The VBB pin should be used only as a bias for the  
ELT21 as its sink/source capability is limited. When used, the VBB pin should be bypassed to ground via a 0.01µF  
capacitor.  
NOTE: Specification in ECL/PECL tables are valid when thermal equilibrium is established.
