Functional Description
Figure 2 is a simplified block diagram, which shows the basic circuit functionality.
The MC44BC380 has separate Vccs and a maximum grounding pattern to ensure high performance in
terms of isolation and leakage.
The MC44BC380 comes in an SO8 package and has a minimum pin count, which reduces cost and
application board space.
NOTE:
A BALUN is required at the input to achieve the stated performance.

This device contains protection circuitry to guard
against damage due to high static voltage or electric
fields. However, precautions must be taken to avoid ap-
plications of any voltage higher than maximum rated
voltages to this high impedance circuit. For proper oper-
ation, input and output voltages should be constrained to
the ranges indicated in the Recommended Operating
Conditions.
aximum ratings are those values beyond which damage to the device may occur. For functional
peration, voltage should be restricted to the Recommended Operating Condition.
