The present invention provides an integrated circuit that has both driver and receiver functions. The circuit of the present invention has two interrelated parts. The first part of the circuit converts true TTL signals to true ECL signals. The second part of the circuit accepts true ECL signals and drives a tri-state true TTL bus. The novel design of the present invention provides a common circuit that acts as an input reference for the circuit that converts true TTL signals to true ECL signals and as a tristate clamp for the circuit that accepts true ECL signals and drives a tri state true TTL bus. Using the same circuit components to perform functions in two separate circuits reduces the …
