IH5045CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5045CPE is a dual-channel CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two DPST normally closed circuits housed in a 16-PDIP package. The device operates on dual 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. Leakage current is limited to 5nA maximum. The component supports through-hole mounting and functions within an ambient temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual independent single-pole double-throw switching paths integrated into a single package
• Normally closed contact configuration for default signal path continuity
• CMOS technology enabling low power consumption and high input impedance

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in multiplexing systems
• Break-before-make switching sequences
• Analog signal isolation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation when sourcing replacements, as the plus sign indicates RoHS compliance while the unmarked version may differ in environmental certification. Confirm the manufacturer source, as production has transferred between Maxim Integrated and Analog Devices. Check the datasheet revision history for any pinout or parameter updates associated with the manufacturing transition. Ensure the procurement channel provides valid traceability documentation for this discontinued component.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed state is required for the idle signal path. The 80-ohm on-resistance suits applications with moderate voltage drops. Verify that the ±4.5V minimum supply aligns with the system power architecture. Consider the 16-pin DIP footprint for legacy board designs requiring through-hole assembly. Evaluate the 400ns switching speed against the signal frequency requirements to ensure adequate response times.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the IH5045 family of dual analog switches. Variants such as the IH5045CPE+ denote environmental compliance differences. Other family members like the IH5045MJE/883B offer military-grade temperature ranges and ceramic packaging. The standard plastic DIP version serves general industrial applications where cost-effective through-hole integration is prioritized over high-frequency performance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The IH5045CPE+ is a direct functional equivalent with updated environmental compliance. For lead-free requirements, verify the availability of the + suffix variant. Cross-reference the IH5045 series datasheet to confirm pin compatibility with alternative suppliers.
