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.
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.

NOTES: 1. All voltage values, except differential input voltage, are with respect to network ground terminal.
2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
3. Common-mode input voltage is the average of the voltages at the A and B inputs.
