IH5143CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5143CPE is a low-power, fast CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole double-throw (SPDT) channels housed in a 16-pin CDIP package. The device operates on dual supplies ranging from ±4.5V to ±18V with a maximum power dissipation of 800mW. Key electrical specifications include a maximum on-resistance of 100 Ohms, a maximum switching current of 30mA, and a maximum supply current of 10µA. Transition times are specified at a maximum of 250ns for turn-on and 150ns for turn-off. The component supports an operating temperature range from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variations such as CPE+ indicate RoHS compliance status which may differ from the base part number. Confirm that the through-hole CDIP-16 package matches the target PCB footprint requirements. Ensure the dual-supply voltage rails align with the ±4.5V to ±18V operational range to prevent device damage or improper switching thresholds during integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring dual-channel SPDT switching with moderate on-resistance constraints. The CMOS architecture suits battery-powered or energy-sensitive applications due to low standby current. Consider the physical dimensions of the CDIP-16 package for mechanical clearance. Evaluate thermal management needs against the 800mW power dissipation limit if driving significant load currents near the 30mA specification.
