Product details

Single SPST analog switch in a tiny SC-70-5

The Maxim Integrated MAX4594EXK+T is a single-pole single-throw normally-open (SPST-NO) analog switch in a 5-pin SC-70-5 package. It routes one signal channel with a 10 Ohm maximum on-resistance and a 300 MHz -3dB bandwidth, making it a fit for RF signal gating, video switching, and high-speed data-path routing in portable or space-constrained boards. Charge injection is rated at 2 pC, which is low enough to avoid glitching sensitive analog inputs in sample-and-hold or precision DAC output stages.

Industrial temperature grade — what it covers

The 500 pA maximum off-leakage keeps signal integrity intact across the temperature span.

Product status is Active and RoHS3 compliant.

Frequently asked questions

Can the MAX4594EXK+T operate with a 3.3V supply?

Yes, the single-supply range is 2V to 5.5V, so 3.3V operation is within spec. The 10 Ohm on-resistance and 300 MHz bandwidth hold across the full supply range.

What is the on-resistance of MAX4594EXK+T?

Maximum on-state resistance is 10 Ohms. That is the worst-case figure across temperature and supply voltage — typical values will be lower.

Is MAX4594EXK+T RoHS compliant?

Yes, it is RoHS3 compliant per the lifecycle record.

What is the closest pin-compatible alternative to MAX4594EXK+T?

Within the same function class, the MAX4594 family shares the same SC-70-5 footprint and SPST-NO configuration. For a direct second-source, check the pin-compatible parts from Texas Instruments or ON Semiconductor in the same package — verify the on-resistance and bandwidth match your signal path before substituting.
