MAX4615CUD-TG068

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4615CUD-TG068 is a quad, low-voltage, high-speed, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches housed in a 14-TSSOP surface-mount package. The device operates from a single +2V to +5.5V supply with a maximum on-resistance of 10Ω and an off-leakage current of 1nA at +25°C. Key electrical parameters include a -3dB bandwidth of 70MHz, charge injection of 6.5pC, and channel-to-channel matching of 200mΩ. Switching times are specified as 12ns for turn-on and 10ns for turn-off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST analog switches configured in a normally closed state
• High-speed performance with 70MHz bandwidth and sub-12ns switching times
• Low on-resistance of 10Ω maximum with tight channel-to-channel matching
• Ultra-low off-state leakage current of 1nA typical

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in battery-powered instrumentation
• Data acquisition systems requiring low distortion
• Communication equipment signal path switching
• Medical instrumentation signal conditioning

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix TG068 against official manufacturer documentation, as standard datasheets typically list MAX4615CUD or MAX4615CUD+ without this trailing code. Confirm RoHS compliance status, noting that non-suffixed or '+' versions may differ. Check component lifecycle status, as older Maxim parts often face obsolescence. Ensure the TSSOP-14 package dimensions match your PCB footprint requirements before ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch configuration is required for low-voltage single-supply applications. Compare against the MAX4614 (normally open) if the logic polarity needs inversion. Consider the MAX4610 series if higher on-resistance (100Ω) is acceptable for lower cost. Verify that the 10Ω on-resistance variation fits within your signal integrity budget for the specific voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4614/MAX4615/MAX4616 family of high-speed analog switches. These devices are pin-compatible with industry-standard 74HC4066 switches but offer superior performance metrics including lower on-resistance and faster switching speeds. The family differentiates primarily by switch state: MAX4614 is normally open, MAX4615 is normally closed, and MAX4616 combines both types.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4614CUD serves as the normally open counterpart within the same package and specification profile. The MAX4616CUD offers a mixed NO/NC configuration. For legacy compatibility, verify if the 74HC4066 meets the stricter speed and resistance requirements, though it lacks the low-voltage optimization.
