ABSTRACT:
A three state Emitter Coupled Logic (ECL) differential bus driver is capable of driving a multiply driven balanced ECL bus which is isolated from a supply voltage V.sub.EE and therefore provides isolation from ground loops, higher performance, lower cost, lower noise, reduced electromagnetic radiation and reduced sensitivity to ground voltage variations.
