IH5049CWE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5049CWE is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual supplies ranging from ±4.5V to ±20V and features a maximum on-resistance of 75 ohms with an 8-ohm channel-to-channel matching. The device exhibits low charge injection of 10pC and a maximum off-state leakage current of 100nA. Switching times are specified at a maximum of 600ns for turn-on and 300ns for turn-off. It supports a DC switch current of 30mA and is housed in a 16-pin PDIP package, operating within a temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as the base part may not meet current environmental standards compared to suffix variants. Validate package integrity upon receipt to ensure pin alignment matches the 16-DIP specification before integration into PCB assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated signal paths are required with moderate on-resistance specifications. Ensure supply voltages remain within the ±4.5V to ±20V range to maintain optimal switching characteristics. Consider thermal dissipation limits if operating near maximum current ratings or ambient temperatures exceeding 70°C.
