Product details

On-resistance and channel matching — signal attenuation budget

The 800mOhm max on-resistance is the headline spec for insertion loss. Channel-to-channel Ron matching is 100mOhm max. Off-leakage is 1nA max, and channel capacitance is 33pF/117pF.

Switching speed and charge injection

Turn-on time is 25ns max, turn-off 20ns max, which supports multiplexer update rates above 20 MHz in scanning applications. The 60pC charge injection is a moderate figure — in a sample-and-hold or precision ADC driver, a downstream buffer or longer acquisition window may be needed to settle the glitch. The -56dB crosstalk at 1MHz gives good channel isolation for audio-frequency multiplexing; at higher frequencies the isolation degrades with the 90MHz bandwidth roll-off.

Package and temperature grade

Housed in a 10-pin TFSOP/MSOP (3.00mm width) package, the MAX4734EUB+T is a surface-mount device for compact PCB layouts. The -40°C to +85°C operating temperature range covers industrial and commercial environments — outdoor telecom cabinets, factory-floor sensor interfaces, and portable instrumentation.

Lifecycle and sourcing

The MAX4734EUB+T carries an Active product status with ROHS3 compliance. For a BOM line that needs a low-voltage SP4T mux, this part is a current-production choice with no immediate obsolescence risk.

Frequently asked questions

What is the crosstalk performance of the MAX4734EUB+T?

The device specifies -56dB crosstalk at 1MHz, which provides adequate channel isolation for audio-frequency multiplexing applications.

What is the closest pin-compatible alternative to the MAX4734EUB+T?

The MAX4734 is a single-source part from Analog Devices; no pin-compatible second source is listed in the available records. For dual-sourcing, evaluate the MAX4734's parametric equivalents from other vendors that offer SP4T switches in a 10-MSOP footprint with similar Ron and supply range.
