MAX4547EEE+T

Analog Switches - Special Purpose Overview

The MAX4547EEE+T is a low-voltage, bidirectional RF/Video switch IC containing two single-pole/double-throw (SPDT) switches. It operates with dual supplies from ±2.7V to ±6V or a single supply from +2.7V to +12V. The device features a maximum on-resistance of 20Ω and a -3dB bandwidth of 300MHz. Turn-on time is typically 150ns, while turn-off time is typically 100ns. It provides off-isolation of -82dB at 10MHz and channel-to-channel crosstalk of -84dB at 10MHz. The component is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• High-frequency performance with 300MHz bandwidth and low insertion loss
• TTL and CMOS logic compatibility with defined input thresholds
• Break-before-make switching action to prevent signal shorting

Analog Switches - Special Purpose Applications

• RF switching systems
• Video signal routing and multiplexing
• High-speed data acquisition circuits
• Test and measurement equipment
• Automated test equipment (ATE)

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EEE+' against the manufacturer's official documentation to confirm lead-free status and industrial temperature rating. Ensure the QSOP-16 package matches the design footprint requirements. Cross-reference the part number with the current Analog Devices catalog to confirm availability and revision status before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring bidirectional SPDT switching with high isolation and wide bandwidth. Verify that the system power supply allows for ±5V operation to achieve optimal on-resistance matching and flatness. Consider board layout constraints, as surface-mount packages are recommended for maintaining high-frequency performance above 5MHz.

Analog Switches - Special Purpose Part Context

The MAX4547EEE+T belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage T-switches. While the MAX4545 offers four SPST switches and the MAX4546 provides dual SPST configurations, the MAX4547 specifically integrates two SPDT switches. This configuration is optimized for applications requiring break-before-make timing and rail-to-rail analog signal handling within low-voltage systems.
