IH5141C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5141C/D is a dual single-pole single-throw (SPST) normally open CMOS analog switch die manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual supplies ranging from ±4.5 V to ±18 V. The device features a maximum on-resistance of 75 Ohms and typical channel-to-channel matching of 5 Ohms. Switching times are specified with a maximum turn-on time of 175 ns and turn-off time of 125 ns. It supports a DC switch current of 30 mA and has a maximum leakage current of 100 nA. The component functions within an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm that the bare die package format meets your assembly capabilities, as standard surface mount or through-hole options may not be available for this specific suffix. Ensure supply chain stability given the discontinuation notice.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when dual isolated analog switching is required in a minimal footprint. Compare the 75 Ohm on-resistance against system voltage drop requirements. Consider the ±4.5 V minimum supply constraint for compatibility with existing power rails. Evaluate the die form factor against wire bonding or flip-chip integration constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the IH5041 series of analog switches. It shares functional similarities with packaged variants like the IH5041CWE but differs in physical implementation. The 'D' suffix indicates a bare die configuration intended for custom packaging or hybrid circuit integration rather than direct PCB mounting.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other Maxim integrated circuit analog switches with compatible pinouts and electrical specifications if redesign is necessary.
