FSAV332
Wide Bandwidth Video Switch
General Description
The Fairchild video switch FSAV32 is a quad high speed
video switch. Low On Resistance allows inputs to be con-
nected to outputs without adding propagation delay or gen-
erating additional ground bounce noise.
The device is organized as four 1-bit switches with sepa-
rate output enable (OE) pins. When OE is LOW, the switch
is ON and Port A is connected to Port B. When OE is
HIGH, the switch is OPEN and a HIGH-Impedance state
exists between the two ports.

Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3:
Unused control inputs must be held HIGH or LOW. They may not
float.

Note 4:
Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the
voltages on the two (A or B Ports).
