MAX459CQH+D

Overview

The MAX459CQH+D is a high-speed video switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a 16-channel SPST configuration housed in a 44-pin LCC package. The device operates on a single 5V supply and supports signal voltages up to 5V. Key electrical specifications include a maximum on-resistance of 35 Ohms, a bandwidth of 150 MHz, and typical switching times of 8 ns for turn-on and 3 ns for turn-off. It provides -90 dB typical off-isolation and handles 10 mA of DC switch current.

Feature Summary

• Provides 16 independent single-pole single-throw analog switches for signal routing
• Features high-speed switching with nanosecond-level transition times
• Includes robust ESD protection rated at 2 kV Human Body Model
• Designed for low power consumption suitable for portable applications

Applications

• Video signal routing and matrix switching systems
• Data acquisition systems requiring multi-channel signal selection
• Test and measurement equipment signal paths
• Industrial control systems for sensor signal multiplexing

Procurement Notes

Verify the specific suffix 'D' indicates the tape and reel packaging variant when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Check for obsolescence or lifecycle changes directly from Analog Devices documentation. Ensure the 44-pin LCC footprint matches the target PCB design constraints before procurement.

Selection Notes

Select this component when a high channel count (16) is required within a compact surface-mount form factor. It is suitable for designs needing moderate bandwidth (150 MHz) and low on-resistance variations. Consider the 44-pin LCC package availability and soldering requirements compared to QFN alternatives if pin count or thermal performance differs from project needs.

Part Context

This part belongs to the MAX459 family of high-speed video switches. The family is characterized by its ability to handle video-frequency signals with minimal distortion. The MAX459 series typically integrates multiple SPST switches into a single IC to reduce board space and simplify signal routing architectures in complex electronic systems.
