IH5045CWE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5045CWE is a CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-SOIC surface-mount package. It features two independent Double-Pole Single-Throw (DPST) normally open circuits within a single chip. The device operates on dual power supplies ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 80 ohms and a channel-to-channel matching of 5 ohms. Switching times are specified with a maximum turn-on time of 400ns and a turn-off time of 200ns. The off-state leakage current is limited to a maximum of 5nA. The component supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates two independent DPST analog switches for signal routing applications
• CMOS technology ensures low power consumption and high input impedance
• Provides precise channel-to-channel matching for balanced signal paths

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring analog signal switching
• Instrumentation equipment for sensor signal multiplexing
• Communication systems for line termination or source selection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWE' against official manufacturer documentation to confirm the SOIC package and commercial temperature grade. Confirm RoHS compliance status as '+CWE' variants typically indicate lead-free construction, but cross-reference with the latest datasheet revision. Check for obsolescence notices or lifecycle changes from Analog Devices/Maxim Integrated before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual DPST configuration is required in a compact surface-mount form factor. Ensure the application voltage does not exceed the ±18V limit. Consider the 80-ohm on-resistance for signal integrity requirements. Verify that the 0°C to 70°C operating range meets environmental constraints. Compare against the DIP variant IH5045CPE+ if through-hole mounting is necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

The IH5045 belongs to the IH504x series of CMOS analog switches from Maxim Integrated, now part of Analog Devices. This series offers general-purpose switching capabilities with standard performance metrics. The 'C' indicates commercial temperature range, while 'W' denotes the wide-body SOIC package. It serves as a solid-state alternative to mechanical relays in low-power switching scenarios.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The IH5045CPE+ is a pin-compatible through-hole replacement offering identical electrical characteristics in a 16-DIP package. For surface-mount needs, verify availability of other members in the IH504x family, such as the IH5041 or IH5047, ensuring configuration matches the specific SPST or DPST requirements.
