4−Bit Differential ECL Bus
to TTL Bus Transceiver
Description
TTL bus transceiver. It is designed to allow the system designer to no
longer be limited in bus speed associated with standard TTL busses.
Using a differential ECL Bus will increase the frequency of operation
and increase noise immunity.
ECL outputs have the ability to drive 25 W, allowing both ends of the
bus line to be terminated in the characteristic impedance of 50 W. The
TTL outputs are specified to source 15 mA and sink 48 mA, allowing
the ability to drive highly capacitive loads.

receivers have special circuitry which detects this disabled condition,
prevents oscillation, and forces the TTL output to the low state. The
noise margin in this disabled state is greater than 600 mV. Multiple

power and ground pins are utilized to minimize switching noise.
