Overview
The PI5A127UEX is a dual single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated, housed in an 8-pin MSOP package. It operates on a single supply voltage ranging from 2V to 6V. The device features a maximum on-resistance of 10Ω at +5V and 18Ω at +3V, with a typical power consumption of 5μW. Switching times include a maximum turn-on time of 15ns and a maximum turn-off time of 7ns at +5V. It supports a -3dB bandwidth of 326MHz and offers off-isolation of -43dB at 10MHz.
Feature Summary
- TTL/CMOS logic compatible input interface
- Low power consumption suitable for battery-powered systems
- Normally closed switch configuration
Applications
- Audio and video switching and routing
- Battery-powered communication systems
- Mechanical relay replacement
- Portable instrumentation
Procurement Notes
Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix 'EX' corresponds to the Pb-free and Green tape and reel packaging format as specified in the datasheet. Ensure compliance with RoHS directives before finalizing procurement orders.
Selection Notes
Select this component for applications requiring low distortion signal routing within a 2V to 6V single supply range. Consider the normally closed state when designing circuit logic. Evaluate thermal dissipation requirements against the 550mW continuous power dissipation limit in the MSOP package.
Part Context
This part belongs to the PI5A127 series of wide bandwidth analog switches. It serves as a high-precision alternative to mechanical relays in compact designs. The device is designed for general-purpose signal switching where low power and small footprint are critical constraints.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify if other manufacturers offer equivalent SPST analog switches with matching on-resistance and voltage specifications.
