IH5047CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5047CPE is a CMOS analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four single-pole double-throw (SPDT) channels configured as dual SPST normally closed switches within a 16-pin SOIC package. The device operates on dual power supplies ranging from ±4.5 V to ±18 V, with a maximum negative supply voltage of -18 V and minimum of -4.5 V. Key electrical parameters include a maximum on-resistance of 80 Ω, a typical off-isolation of 50 dB, and an on-resistance matching specification of 5 Ω. The component supports a nominal negative supply voltage of -15 V and functions within a commercial temperature range.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four-channel CMOS architecture providing dual SPST normally closed switching functionality
• Low on-resistance characteristic with tight channel-to-channel matching for signal integrity
• Operates on standard dual supply voltages compatible with common industrial logic levels

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in multiplexed data acquisition systems
• Audio and video signal path switching applications
• Test and measurement equipment requiring low-distortion analog switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPE against the official datasheet to confirm the SOIC-16 package and commercial temperature grade. Confirm RoHS compliance status as historical Maxim data may vary. Check for obsolescence notices or product change notifications prior to procurement, as this component series has been subject to lifecycle management actions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the IH5047CPE when a normally closed configuration is required for four independent analog signals. Ensure the system voltage does not exceed the ±18 V absolute maximum rating. Compare on-resistance and leakage specifications against alternative parts if high-frequency performance or ultra-low power consumption is critical for the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the IH504x series of CMOS analog switches, which includes variants like the IH5043 and IH5045. These components are designed for general-purpose analog signal switching. The manufacturer, now part of Analog Devices, previously operated under the Maxim Integrated brand, influencing legacy documentation naming conventions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include the IH5043CJE and IH5045CPE. Verify that the replacement part maintains the normally closed state and matches the package type. Cross-reference datasheets for any changes in on-resistance or switching speed characteristics.
