RS2227XN

Overview

The RS2227XN is a high-speed, low-power dual double-throw (DPDT) analog switch manufactured by Runic Technology. It operates within a supply voltage range of +1.8V to +5.5V and features a single enable pin for high-impedance state control. Key electrical parameters include a typical on-resistance (Ron) of 6Ω, an on-capacitance (Con) of 7pF, and a -3dB bandwidth of 550MHz. The device exhibits fast switching times with an on-time (ton) of 20ns and an off-time (toff) of 15ns. Additional specifications include a propagation delay (tpd) of 350ps, charge injection of 11pC, and operation across an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports rail-to-rail input and output signal handling
• Features break-before-make switching action to prevent signal glitches
• Provides low power consumption with maximum microamp-level standby current

Applications

• Signal routing for USB 1.0, 1.1, and 2.0 interfaces
• Audio signal path switching
• Telecommunications equipment signal management

Procurement Notes

Verify the specific ordering suffix 'XN' corresponds to the MSOP-10 package configuration when sourcing components. Ensure that the procurement documentation explicitly confirms the manufacturer as Runic Technology to avoid counterfeit parts. Cross-reference the part number against official distributor catalogs to confirm availability in tape-and-reel packaging formats suitable for surface-mount assembly processes.

Selection Notes

Select this component for applications requiring high-speed signal multiplexing with minimal distortion. The 6Ω on-resistance and 550MHz bandwidth make it suitable for maintaining signal integrity in high-frequency data lines. Consider the 10-MSOP package size for space-constrained designs. Verify that the 1.8V to 5.5V operating range aligns with the system's power supply architecture before integration.

Part Context

The RS2227XN belongs to Runic Technology's series of special purpose analog switches designed for USB and general-purpose signal routing. It serves as a compact solution for managing multiple signal sources or destinations in portable electronics and communication devices. The device complements other switches in the family by offering DPDT functionality in a small footprint, facilitating efficient board layout for complex signal paths.
