description
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.

NC – No internal connection
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.
THE MC3452 IS NOT
RECOMMENDED FOR NEW DESIGN
