Overview
The UM9636 is a high-speed, low-power dual single-pole/double-throw (SPDT) analog switch manufactured by Union Semiconductor International Limited. Designed for signal routing and multiplexing applications, it operates from a single +2.7V to +12V supply voltage. The device features a -3dB bandwidth of 720MHz, ensuring efficient high-frequency performance. It is housed in a compact 10-QFN (WQFN10) package with dimensions of 1.8x1.4mm, facilitating space-constrained PCB layouts. The IC provides two independent switching circuits with an on-resistance of 125 Ohms, suitable for precise analog signal control.
Feature Summary

Procurement Notes
Verify the manufacturer part number UM9636 against official Union Semiconductor documentation to ensure authenticity. Confirm that the received components match the specified 10-QFN package type and electrical characteristics. Check for RoHS compliance status as indicated in official datasheets. Ensure storage and handling procedures adhere to industry standards for sensitive integrated circuits to prevent damage prior to assembly.
Selection Notes
Select the UM9636 when dual-channel SPDT switching is required within a limited board area. Consider this component for designs operating between +2.7V and +12V single supplies where low power consumption is critical. The 720MHz bandwidth makes it suitable for high-frequency analog signals. Evaluate the 125 Ohm on-resistance against system impedance requirements to ensure signal integrity is maintained during switching operations.
Part Context
Union Semiconductor International Limited produces the UM9636 as part of its analog switch portfolio. This component belongs to the category of high-speed dual SPDT switches. It is designed to replace or upgrade existing solutions requiring compact, low-power signal routing capabilities. The product line focuses on providing reliable analog switching for modern electronic devices with stringent size and power constraints.
Replacement Considerations
