ABSTRACT:
Driver and receiver circuits for a differential-signal electrical interface contain comparators and resistive networks to eliminate the need for operational amplifiers, thus lowering cost and raising reliability. The preferred embodiments for the driver and receiver are optimized for use with transistor-transistor logic (TTL) signals and the International Telegraph and Telephone Consultative Committee (CCITT) 1985 Recommendation V.35, which recommendation was designed for use with wideband modems.
