MAX4456EPL

Analog Switches - Special Purpose Overview

The MAX4456EPL is a low-cost, 8x8 video crosspoint switch manufactured by Analog Devices Inc./Maxim Integrated. It features an internal matrix of T-switches connecting eight video inputs to eight buffered outputs in any combination. Each output includes a high-speed unity-gain amplifier with a 250V/µs slew rate, capable of driving 400Ω and 20pF loads at 2.6Vp-p. The device offers a 65MHz -3dB bandwidth and supports serial or parallel digital interfaces. It provides three-state output capability and power-saving disable features. Packaged in a 40-pin DIP, it operates within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Provides an 8x8 switch matrix for routing any input channel to any output channel
• Features internal buffers with high-speed slew rates for video signal integrity
• Includes three-state output capability and programmable active loads for array expansion
• Offers low crosstalk and high isolation through separated quiet power supplies

Analog Switches - Special Purpose Applications

• Video surveillance systems requiring multiple camera routing
• Broadcast video switching matrices
• Medical imaging equipment display routing
• Industrial process control video monitoring

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix EPL confirms the PDIP-40 package and industrial temperature grade. Confirm RoHS compliance status as older Maxim parts may vary. Check current availability as this component series has been subject to discontinuation notices. Ensure the supplier provides valid traceability documentation for critical applications.

Analog Switches - Special Purpose Selection Notes

Select the MAX4456EPL when an 8x8 configuration is required for video signals. Consider the MAX4359 for smaller 4x4 matrices or the MAX4360 for 8x4 setups if pin count reduction is needed. Verify that the 65MHz bandwidth meets the specific video frequency requirements. Evaluate the need for three-state outputs if bus sharing is necessary in the system design.

Analog Switches - Special Purpose Part Context

The MAX4456 serves as a low-cost, pin-for-pin compatible alternative to the popular MAX456. It belongs to a family of low-cost video crosspoint switches designed to reduce component count and board space. The device simplifies layout with straight-through pinouts and separates channels with quiet power supplies to minimize interference.

Analog Switches - Special Purpose Replacement Considerations

The MAX456 is a direct pin-compatible alternative with better DC specifications. For smaller matrices, consider the MAX4359 (4x4) or MAX4360 (8x4). External buffering with the MAX4395 operational amplifier can be used if higher drive capability is required beyond the internal buffer limits.
