Overview
The PI5A393AP is a monolithic quad analog switch designed for low-voltage, single-supply operation within the +2V to +6V range. It features two normally open (NO) and two normally closed (NC) switches per package. The device guarantees an on-resistance of less than 12 ohms at a +5V supply and maintains channel matching within 2 ohms. It supports rail-to-rail analog signal ranges and offers high-speed switching with turn-on times under 20ns. The component operates over an industrial temperature range from -40°C to +85°C.
Feature Summary
- Combines two normally open and two normally closed SPST channels in a single package
- Provides rail-to-rail analog signal handling capability across the full supply voltage range
- Ensures low distortion through tight on-resistance matching between channels
- Compatible with standard TTL and CMOS logic input levels
Applications
- Audio and video signal switching and routing systems
- Battery-powered communication equipment
- Computer peripheral interface circuits
- Portable instrumentation devices
Procurement Notes
Verify the specific suffix 'P' against the manufacturer's current documentation to confirm the package type and temperature grade. Confirm availability status as older datasheets may reference legacy ordering codes or discontinued variants. Ensure the selected part matches the required QSOP or SOIC footprint for your PCB layout.
Selection Notes
Select this component when a mixed configuration of normally open and normally closed analog paths is required. Verify that the system supply voltage falls within the specified +2V to +6V window. Check that the load current requirements do not exceed the maximum output current ratings defined in the electrical characteristics table.
Part Context
This device belongs to the PI5A39X family of precision wide-bandwidth analog switches. It shares pin compatibility with other industry-standard parts like the DG3XX and MAX39X series. The family includes variations such as the PI5A391A for all NC switches and the PI5A392A for all NO switches.
Replacement Considerations
Public confirmed substitute part numbers include DG393 and MAX393. These components offer similar quad SPST configurations with mixed NO/NC states and comparable electrical performance metrics.
