MAX4517CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4517CPA is a single-pole/single-throw (SPST), CMOS, low-voltage, dual-supply analog switch with very low on-resistance. It operates continuously with dual supplies between ±1V and ±6V or a single supply from +2V to +12V. The device handles rail-to-rail analog signals with an off-leakage current maximum of 1nA at +25°C and 20nA at +85°C. It features guaranteed on-resistance of 20Ω with ±5V supplies, low charge injection of 20pC max, and fast switching speeds with turn-on time of 100ns and turn-off time of 75ns. The digital input is referenced to the positive power supply and is CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CPA' against the manufacturer's official documentation to confirm the package type and temperature range. Ensure that the component meets all required electrical specifications for the intended application environment before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring dual-supply operation and low on-resistance. Consider the MAX4516 if a normally open configuration is needed instead of the normally closed MAX4517. Verify compatibility with single-supply systems using pin-compatible alternatives like the MAX4514/MAX4515 if necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4517CPA belongs to the MAX4516/MAX4517 family of dual-supply, low-on-resistance, SPST, CMOS analog switches. This series is designed for low-voltage applications and offers high performance in terms of leakage current and switching speed. The CPA variant specifically denotes an 8-pin plastic DIP package with a commercial temperature range.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

For a normally open configuration, consider the MAX4516CPA. For single-supply applications, the MAX4514CPA or MAX4515CPA are pin-compatible alternatives. Higher temperature range options include the MAX4517EPA (-40°C to +85°C).

Analog Switches, Multiplexers, Demultiplexers FAQ

Is the MAX4517CPA TTL compatible?

No, the logic-level thresholds are CMOS compatible but not TTL compatible. Connecting V+ to +3V and logic-level pins to +5V TTL signals can violate absolute maximum ratings.

What is the default state of the MAX4517CPA switch?

The MAX4517 is a normally closed (NC) switch. When the input is low, the switch is on; when the input is high, the switch is off.

How does the off-isolation change with frequency?

At 10MHz, off-isolation is about -48dB in 50Ω systems. Off-isolation decreases approximately 20dB per decade as frequency increases due to capacitive coupling.
