CLC532
High Speed 2:1 Analog Multiplexer
General Description
The CLC532 is a high speed 2:1 multiplexer with active input
and output stages. The CLC532 innovative design employs
a closed loop design which dramatically improves accuracy.
This monolithic device is constructed using an advanced
high performance bipolar process.
The CLC532 has been specifically designed to provide set-
tling times of 17ns to 0.01%. Fast settling time, coupled with
the adjustable bandwidth, and channel-to-channel isolation
is better than 80dB
@
10MHz. Low distortion (-80dBc) makes
the CLC532 an ideal choice for infrared and CCD imaging
systems and spurious signal levels make the CLC532 a very
suitable choice for both I/Q processors and receivers.
The
CLC532
is
offered
in
two
industrial
versions,
CLC532AJP\AJE, specified from -40C to +85C and pack-
aged in 14-pin plastic DIP14-pin and SOIC packages.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation.
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: The CLC532 does not require external C
COMP
capacitors for proper operation.
Note 4: Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit maybe impaired. functional
operability under any of these conditions is not necessarily implied. Exposure to maximum ratings for extended periods may affect device reliability.
Note 5: AJ: 100% tested at +25C, sample tested at +85C
