The -3 dB bandwidth of 85 MHz and crosstalk of -65 dB at 10 MHz make it suitable for video, RF, and high-speed data acquisition where signal integrity matters. Maximum turn-on time is 18 ns, turn-off is 7 ns, so the mux can handle multiplexing rates into the tens of megahertz without introducing timing skew between channels. Charge injection is 13 pC — low enough that sample-and-hold circuits and precision ADC front-ends won't see a significant glitch when the switch changes state. Leakage current is a maximum of 250 pA off-state, which keeps the signal path clean in high-impedance applications like photodiode amplifiers or pH probes. ## Package and temperature range — field-fit reality Surface-mount only; not a socketed part, so a field swap means hot air or a reflow station. ## RoHS note — lead content affects assembly compliance If your BOM requires lead-free solder per EU RoHS or similar regulations, you will need an exemption or a leaded assembly process.","metaTitle":"MAX4639EGE Dual 4:1 Analog Mux, 3.5 Ohm, 85MHz","metaDescription":"MAX4639EGE dual 4:1 analog multiplexer, 3.5 ohm max on-resistance, 85MHz bandwidth, -65dB crosstalk at 10MHz.
