IH5049CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5049CPE+ is a dual-channel CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole single-throw (SPST) normally open circuits housed in a 16-pin plastic DIP package. The device operates on dual supplies ranging from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 75 ohms, a channel-to-channel matching of 8 ohms, and a typical charge injection of 10pC. Switching times are specified at 600ns for turn-on and 300ns for turn-off. The component supports a maximum leakage current of 100nA and functions within an ambient temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration providing independent signal path control
• Low charge injection characteristics suitable for precision applications
• CMOS technology ensuring low power consumption

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Audio switching matrices
• Instrumentation front-end multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the RoHS compliance status carefully, as historical records indicate the non-plus suffix version was non-compliant while the plus suffix denotes compliance. Confirm the specific manufacturing date code against the latest product change notices from Analog Devices or Maxim Integrated to ensure material consistency. Check for any obsolescence notices or lifecycle changes that may affect long-term supply availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel, normally open analog switch with moderate on-resistance is required. Ensure the application voltage does not exceed the ±20V limit. Consider the 16-DIP package constraints for PCB layout. Compare against the IH5045CPE+ if normally closed operation is needed instead, or the IH5049CPE if leaded versions are acceptable despite potential regulatory restrictions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the IH504x series of CMOS analog switches from Maxim Integrated, now part of Analog Devices. The series includes variants like the IH5041, IH5042, and IH5045, differing primarily in contact configuration (normally open vs. normally closed) and packaging options. The IH5049 specifically offers dual SPST normally open channels, distinguishing it from the DPST NC configuration of the IH5045.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The IH5049CPE+ serves as the direct RoHS-compliant replacement for the obsolete IH5049CPE. Verify pinout compatibility before substitution.
