Overview
The RS2254XQ is a quad single-pole single-throw (SPST) analog switch manufactured by Runic Technology, housed in a 14-TSSOP surface-mount package. It operates on a single supply voltage ranging from 2.5V to 5.5V. The device features a maximum on-resistance of 30 ohms with a typical channel-to-channel matching of 1 ohm. Electrical specifications include a -3dB bandwidth of 180MHz, turn-on time of 90ns, and turn-off time of 70ns. Additional parameters specify a charge injection of 6pC, off-state leakage current of 100nA, and crosstalk of -110dB at 1MHz. It supports an operating temperature range of -40°C to 125°C.
Feature Summary
- Integrates four independent SPST switches within a compact 14-pin TSSOP footprint for space-constrained designs.
- Provides high-speed signal routing capabilities with a 180MHz bandwidth and sub-100ns switching times.
- Ensures signal integrity through low on-resistance variation and minimal charge injection effects.
Applications
- Signal routing in portable battery-powered equipment
- Sample-and-hold circuits requiring fast settling times
- Data acquisition systems utilizing multiplexed inputs
Procurement Notes
Verify the manufacturer part number RS2254XQ against official Runic Technology documentation to confirm pinout compatibility and electrical ratings. Ensure the selected package variant matches the required thermal and mechanical constraints for the target PCB layout. Cross-reference RoHS compliance status if environmental regulations apply to the final assembly process.
Selection Notes
Select this component when designing circuits that require multiple isolated signal paths controlled by digital logic levels. The 2.5V to 5.5V supply range makes it suitable for modern low-voltage microcontroller interfaces. Evaluate the 30-ohm on-resistance against the load requirements to ensure acceptable signal attenuation. Consider the 14-TSSOP package dimensions during the mechanical design phase.
Part Context
This component belongs to the analog switch category within Runic Technology's interface integrated circuit portfolio. It serves as a solid-state alternative to electromechanical relays in applications demanding rapid switching cycles without physical wear. The device complements other signal conditioning components such as operational amplifiers and data converters in mixed-signal systems.
Replacement Considerations
Consult official substitution guides for compatible quad SPST switches with similar 30-ohm resistance and 14-TSSOP packaging. Verify that any alternative device maintains equivalent voltage ranges and switching speeds to prevent performance degradation in existing designs.
