MAX456CQH+TD

Analog Switches - Special Purpose Overview

The MAX456CQH+TD is a video crosspoint switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features a 44-LCC (J-Lead) package and operates within a temperature range of -40°C to +85°C. The component supports single supply voltages from 2.7V to 12V or dual supplies of ±2.7V to ±6V. Key electrical parameters include a maximum on-resistance of 60 Ohms, a bandwidth of 350 MHz, and turn-on/turn-off times of 150ns and 100ns respectively. It provides typical off-isolation of -82 dB and handles up to 10 mA of DC switch current.

Analog Switches - Special Purpose Feature Summary

• Provides high-bandwidth signal routing for video applications with low distortion characteristics
• Features bidirectional switching capability allowing flexible signal path configuration
• Incorporates break-before-make switching action to prevent signal glitches during transitions

Analog Switches - Special Purpose Applications

• Video distribution systems
• Signal routing in multimedia equipment
• Test and measurement instrumentation

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CQH' against the manufacturer's official part numbering system to confirm pinout and package compatibility. Ensure the '+T' designation aligns with your required tape-and-reel quantity specifications. Cross-reference the RoHS status and REACH compliance data provided in the latest datasheet revision to meet regulatory requirements for your manufacturing region.

Analog Switches - Special Purpose Selection Notes

Select this component when a compact crosspoint solution is required for video signals. The 44-pin LCC package offers a balance of pin count and board space efficiency compared to larger DIP options. Consider the 60 Ohm on-resistance and 350 MHz bandwidth as sufficient for standard definition video frequencies. Evaluate thermal dissipation capabilities if operating at the upper limits of the voltage range.

Analog Switches - Special Purpose Part Context

This device belongs to the MAX456 series of video crosspoint switches designed for analog signal routing. It is distinct from the MAX4569 SPST switch and the MAX4566 quad switch. The MAX456 family typically integrates multiple switches into a single crosspoint matrix architecture, differing from the simple multiplexer configurations found in other Maxim Integrated interface products.
