FFF CompatibilityThe alternative is packaged in a 144-LQFP, which is physically larger and has a completely different pin layout compared to the 128-pin TQFP of the MAX4357.The package size is 20x20mm (144-LQFP) compared to the original 14x20mm (128-TQFP), requiring layout modifications.It meets or exceeds all core electrical and functional specifications, providing a full 32x16 nonblocking matrix with dual-supply compatibility matching the original.The package pin count is significantly lower (80 pins vs 128 pins), resulting in completely incompatible pinouts.The 80-TQFP package has a much smaller physical footprint than the 128-TQFP, necessitating board layout adjustment.It operates only on a single +5V supply (no dual ±5V rails) and uses an I2C control interface instead of the original 3-wire SPI-compatible interface.
AI Summary

MAX4357ECD+ by Analog Devices: Video Switch IC 1 Channel 128-LQFP (14x20).

The LMH6585VV/NOPB is a high-performance 32x16 video crosspoint switch that perfectly supports the ±3V to ±5V dual-supply rails of the MAX4357. While it features a significantly higher bandwidth of 400 MHz and requires a PCB redesign due to its 144-LQFP package, it serves as an excellent functional second-source replacement. This active part is currently stocked and supported through specialty distributors like Rochester Electronics.

  • Perfect voltage range match supporting ±3V to ±5.5V dual-rail supplies
  • Significantly higher bandwidth (400 MHz vs 70 MHz) which reduces signal distortion
  • Buffered inputs and outputs similar to the original architecture
  • Requires full PCB redesign due to package and footprint mismatch (144-LQFP vs 128-TQFP)
  • Higher power consumption due to the wider 400 MHz bandwidth capability

The LMH6586VS/NOPB offers a more compact 80-pin alternative for single-supply +5V systems. It matches the 32x16 nonblocking matrix architecture with 66 MHz bandwidth and adds integrated DC-restore clamps, but lacks dual-supply support and uses I2C instead of SPI. It is currently active and available through Rochester Electronics.

  • Smaller 80-pin TQFP package reduces board space requirements
  • Integrated AC-coupled DC restore clamps on each input simplifies front-end design
  • Sufficient 66 MHz bandwidth very close to the target's 70 MHz bandwidth
  • No dual-rail (±3V to ±5V) supply support, restricting use to single +5V analog rails
  • Control interface is I2C instead of SPI/3-wire serial, requiring host microcontroller firmware changes

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
