It routes one analog or digital signal through a 35 Ohm max on-resistance channel, with switching times of 175 ns (turn-on) and 145 ns (turn-off). The -85 dB crosstalk at 1 MHz keeps channel isolation clean in multiplexed audio or precision measurement chains. It operates from a single supply of 10 V to 30 V or dual supplies of ±4.5 V to ±20 V, covering common industrial and test-equipment rails. ## On-resistance and charge injection — what they mean for your signal The 35 Ohm max on-resistance sets the insertion loss and voltage drop across the switch. For a 1 V signal into a 10 kΩ load, the loss is under 0.35% — negligible for most analog paths. The 3 pC charge injection matters when the switch drives a high-impedance sample-and-hold or integrator; a 10 pF hold capacitor sees a 300 µV glitch, which may need settling time in a 12-bit system. Channel-to-channel matching of 2 Ohm max ensures consistent attenuation when multiple switches are used in parallel or in a gain-setting network. ## Leakage and capacitance — guarding the off-state Off-state leakage is 250 pA max, and channel capacitance is 8 pF on both source and drain pins. At 1 MHz, the 8 pF capacitance presents about 20 kΩ of reactive impedance — fine for low-frequency analog, but worth budgeting in RF or high-speed digital multiplexing where the off-channel can couple signal through the parasitic path. ## Temperature range and environment Rated for -40°C to 85°C ambient, this switch suits outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay control modules. The 8-SOIC package is surface-mount, compatible with standard reflow profiles. ROHS3 compliant, no exemptions for lead or cadmium. ## Sourcing and lifecycle No official second-source or pin-compatible alternate is listed in the manufacturer's cross-reference, so dual-sourcing would require a parametric search for a similar SPST-NC switch in the same package.","metaTitle":"MAX317ESA+ SPST-NC Analog Switch, 35Ohm, 8-SOIC","metaDescription":"MAX317ESA+ SPST-NC analog switch, 35Ohm max on-resistance, -85dB crosstalk at 1MHz, -40°C to 85°C.
