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 also 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 settling times

of 17ns to 0.01%. This, coupled with the adjustable noise-bandwidth,

makes the CLC532 an ideal choice for infrared and CCD imaging

systems.

Channel-to-channel isolation is better than 80dB @

10MHz. Low distortion (80dBc) and spurious signal levels make the

CLC532 a very suitable choice for both I/Q processors and receivers.

The CLC532 is offered over both the industrial and military temperature

ranges. The Industrial versions, CLC532AJP\AJE\AID, are specified

from -40°C to +85°C and are packaged in 14-pin plastic DIP's, 14-pin

SOIC's and 14-pin Side-Brazed packages. The extended temperature

versions, CLC532A8B/A8D/A8L-2, are specified from -55°C to +125°C

and are packaged in a 14-pin hermetic DIP and 20-terminal LCC

packages. (Contact factory for LCC and CERDIP availability.)
