Overview
The FSA2467UMX-FS is a dual double-pole double-throw (DPDT) analog switch manufactured by Fairchild Semiconductor, now part of onsemi. It operates within a supply voltage range of 1.65 V to 4.3 V and supports a maximum DC switch current of 350 mA. The device features a maximum on-resistance of 0.55 Ω with a matching specification of 0.03 Ω. Key electrical parameters include an off-isolation of 75 dB, a maximum propagation delay of 50 ns, and a maximum turn-off time of 32 ns. It functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual DPDT configuration for efficient signal routing in compact designs
- Low on-resistance ensures minimal signal loss and power dissipation
- High off-isolation prevents signal leakage between channels
- Fast switching speeds support high-frequency data transmission
Applications
- Portable multimedia devices requiring low-voltage signal switching
- USB hub architectures for port management
- Mobile phone peripheral interface circuits
Procurement Notes
Verify the manufacturer designation carefully, as Fairchild Semiconductor was acquired by onsemi. Confirm that the suffix FS corresponds to the specific packaging or tape-and-reel variant required for your assembly process. Cross-reference the datasheet revision to ensure compatibility with your design specifications.
Selection Notes
Select this component when a dual-channel DPDT switch is needed for low-voltage applications below 4.3 V. Ensure the PCB layout accommodates the QCC16 package dimensions. Verify that the required on-current does not exceed the 350 mA limit and that the operating environment stays within the specified temperature range.
Part Context
This component belongs to the FSA2467 series of low-voltage analog switches. It shares functional similarities with other members like the FSA2467MPX but differs in package type. The series is designed for portable electronics where space and power efficiency are critical constraints.
Replacement Considerations
The FSA2467MPX is a documented alternative within the same family. Verify pinout compatibility and package differences before substitution. Ensure the replacement meets the same voltage and current ratings.
