LT1205CS#TRPBF

Analog Switches - Special Purpose Overview

The LT1205CS#TRPBF is a dual 4-input, 2-output video multiplexer housed in a 16-lead narrow body SO package. It features a –3dB bandwidth of 150MHz and 0.1dB gain flatness up to 30MHz. The device operates on supply voltages ranging from ±5V to ±15V with a typical slew rate of 300V/μs. Electrical characteristics include channel-to-channel switching time of 25ns, output offset voltage of 10mV (max 30mV), and input bias current of 0.6μA (max 5μA). Differential gain and phase are limited to 0.02% and 0.02° respectively. Supply current ranges from 11.6mA to 28mA depending on the enable state.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Ensure the ordering code matches the required lead-free manufacturing standards. Confirm availability through authorized distributors as stock levels fluctuate. Validate that the component meets RoHS compliance requirements for your region before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when high bandwidth and low distortion are critical for video signal integrity. The dual architecture allows efficient space utilization in multi-channel designs. Consider the thermal dissipation characteristics of the SO package if operating near maximum junction temperatures. Verify logic level compatibility with the driving control circuitry to ensure reliable switching performance.

Analog Switches - Special Purpose Part Context

This part belongs to the LT1203/LT1205 family of wideband video multiplexers manufactured using a complementary bipolar process. While the LT1203 provides a single 2-input configuration, the LT1205 offers a dual version designed for higher density applications. Both share similar electrical specifications but differ in pin count and internal topology to support their respective channel counts.
