G4979A - 75108 Dual Line Receiver

These circuits are TTL-compatible, high-speed line receivers. Each is a monolithic dual circuit featuring two independent channels. They are designed for general use, as well as for such specific applications as data comparators and balanced, unbalanced, and party-line transmission systems. These devices are unilaterally interchangeable with and are replacements for the 55107, 75107, and 75108, but offer diode-clamped strobe inputs to simplify circuit design. The 75107 is characterized for operation from 0°C to 70°C.
