Texas Instruments MC3552
The MC3450, MC3550, MC3452, and MC3552 are quad differential line receivers designed for use in balanced and unbalanced digital data transmission. The MC34/3550 and MC34/3552 are the same except that the MC3450 and MC3550 have 3-state outputs whereas the MC3452 and MC3552 have open-collector outputs, which permit the wire-AND function with similar output devices. The 3-state and opencollector outputs permit connection directly to a bus-organized system.MC3450, MC3452, MC3550, MC3552 QUAD DIFFERENTIAL LINE RECEIVERS D Four Independent Receivers With Common Enable Input D High Input Sensitivity . . . 25 mV Max D High Input Impedance D MC3450 and MC3550 Have 3-State Outputs D MC3452 Has Open-Collector Outputs D Glitch-Free Power-Up/Power-Down Operation description The MC3450, MC3550, MC3452, and MC3550 are designed for optimum performance when used with either the MC3453 or MC3553 quad differential line driver or SN75109A, SN75110A, and SN75112 dual differential drivers. The MC3450 and MC3452 are characterized for operation from 0°C to 70°C. The MC3550 and MC3552 are characterized for operation over the full military temperature range of − 55°C to 125°C.
