Overview
The FSA1153UCX is a single-channel, double-pole triple-throw (DP3T) analog switch manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.5 V and features a maximum on-resistance of 2 ohms with a channel-to-channel matching of 200 milliohms. The device supports a -3 dB bandwidth of 500 MHz and exhibits low leakage current, with a maximum off-state leakage of 100 nA. Switching times are characterized by a typical turn-on time of 80 µs and a typical turn-off time of 400 ns. It is housed in a compact 12-WLCSP package measuring 1.41 x 1.575 mm and functions reliably across an ambient temperature range of -40°C to +85°C.
Feature Summary
- Integrates a DP3T switching topology for signal routing applications
- Provides high-speed performance with 500 MHz bandwidth capability
- Ensures signal integrity through low on-resistance and tight channel matching
Applications
- Signal multiplexing and demultiplexing in portable devices
- Audio and video signal path switching
- USB port selection and management circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly from the manufacturer's datasheet or material declaration before finalizing procurement plans. Ensure that the selected variant matches the required operating temperature range for the intended application environment.
Selection Notes
Select this component when a single-channel DP3T configuration is required for low-voltage analog signal routing. Consider the 2-ohm on-resistance and 500 MHz bandwidth limits to ensure compatibility with the target signal frequencies and impedance requirements. Verify that the 12-WLCSP footprint fits within the available PCB area constraints.
Part Context
This component belongs to the FSA series of analog switches from onsemi, designed for mobile and portable electronics. It serves as a compact solution for managing multiple signal sources or destinations in space-constrained designs. The WLCSP packaging allows for minimal board space usage compared to traditional surface-mount packages.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the DP3T configuration, 2.7V-5.5V supply range, and compatible 12-WLCSP footprint.
