LT1203CS8#PBF

Analog Switches - Special Purpose Overview

The LT1203CS8#PBF is a wideband 2-input video multiplexer manufactured by Analog Devices Inc. in an 8-lead SOIC package. It features a –3dB bandwidth of 150MHz and 0.1dB gain flatness up to 30MHz. The device operates on dual supplies ranging from ±5V to ±15V with a typical supply current of 14mA when enabled. Key electrical parameters include a high slew rate of 300V/μs, channel-to-channel switching time of 25ns, and propagation delay of 2.9ns. It provides greater than 90dB channel separation at 10MHz, differential gain error of 0.02%, and differential phase error of 0.02°. The output impedance is typically 20Ω when enabled and rises to 10MΩ when disabled.

• Outputs protected against short circuits to ground

Analog Switches - Special Purpose Applications

• Broadcast quality video multiplexing
• Picture-in-picture switching
• HDTV systems
• Computer graphics
• Video routers

Analog Switches - Special Purpose Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the part number matches the specific suffix requirements for the SOIC-8 package. Ensure compliance with RoHS directives as indicated in the product specifications. Check for any industrial grade availability if extended temperature ranges beyond commercial limits are required.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high bandwidth video switching with minimal signal degradation. Consider the ±5V to ±15V supply range compatibility with standard video systems. Evaluate the 25ns switching speed against system timing requirements. Ensure PCB layout supports the high-frequency performance by minimizing stray capacitance and utilizing ground planes.

Analog Switches - Special Purpose Part Context

The LT1203 is part of the LT1203/LT1205 family of 150MHz video multiplexers. While the LT1203 provides a single 2-input switch, the LT1205 offers a dual configuration. Both utilize Linear Technology's complementary bipolar process for high-speed operation. The CS8 suffix denotes the commercial temperature range variant housed in an 8-lead plastic SOIC package.
