CLC533
High-Speed 4:1 Analog Multiplexer
General Description
Features
■
The CLC533 is a high-speed 4:1 multiplexer employing active
input and output stages. The CLC533 also employs a closed-loop
design which dramatically improves accuracy over conventional
analog multiplexer circuits. This monolithic device is constructed
using an advanced high-performance bipolar process.
12-bit settling (0.01%) – 17ns
■
Low noise – 42µVrms
■
Isolation – 80dB @ 10MHz
■
110MHz -3dB bandwidth (A = +2)

Low distortion – 80dB @ 5MHz
Adjustable bandwidth – 180MHz (max)
The CLC533 has been specifically designed to provide a 24ns
settling time to 0.01%. This coupled with the adjustable band-
width, makes the CLC533 an ideal choice for infrared and CCD
imaging systems, with channel-to-channel isolation of 80dB @
10MHz. Low distortion and spurious signal levels (-80dBc) make
the CLC533 a very suitable choice for I/Q processors in radar
receivers.
Applications
■
Infrared system multiplexing
■
CCD sensor signals
■
Radar I/Q switching
■
High definition video HDTV

Test and calibration
The CLC533 is offered over both the industrial and military tem-
perature ranges. The industrial versions, CLC533AJP\AJE\AIB,
are specified from -40°C to +85°C and are packaged in 16-pin
plastic DIPs, SOIC’s and CERDIP packages. The extended tem-
perature versions, CLC533A8B/A8L-2A, are specified from -55°C
to +125°C and are packaged in 16-pin CERDIP and 20-terminal
LCC packages.
