Overview
The PI5A393AW is a precision wide bandwidth quad analog switch from Diodes Incorporated, housed in a 16-pin SOIC package. It operates on a single supply voltage ranging from +2V to +6V. The device integrates two normally closed (NC) and two normally open (NO) switches per package. Key electrical specifications include a typical on-resistance of 6 ohms at 5V supply with a maximum of 18 ohms. The turn-on time is typically 10 ns, while the charge injection is typically 4 pC. The component supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates two normally closed and two normally open analog switches within a single monolithic package for mixed signal routing.
- Provides rail-to-rail analog signal handling capability across the full single-supply voltage range.
- Ensures low distortion through tight on-resistance matching between channels and minimal on-resistance flatness.
- Features high-speed switching characteristics combined with very low crosstalk for high-frequency signal integrity.
Applications
- Audio and video signal switching and routing systems
- Battery-powered communication equipment
- Computer peripheral interface circuits
- Telecommunications signal processing
- Portable instrumentation requiring mechanical relay replacement
Procurement Notes
Verify the specific suffix 'W' corresponds to the 16-pin narrow-body SOIC package configuration as documented in the official datasheet. Confirm that the manufacturer accepts this part number designation for procurement orders. Ensure compatibility with industrial temperature ratings before finalizing supply chain agreements.
Selection Notes
Select the PI5A393AW when a design requires a combination of both normally open and normally closed analog switches in one package. This component is suitable for applications demanding high bandwidth exceeding 200 MHz and low charge injection to prevent signal artifacts. Consider the 16-pin SOIC footprint for surface-mount assembly requirements.
Part Context
This component belongs to the PI5A39X family of precision wide bandwidth quad analog switches manufactured by Diodes Incorporated. The family includes the PI5A391A with four normally closed switches and the PI5A392A with four normally open switches. All variants share similar electrical performance characteristics and pin configurations.
Replacement Considerations
Public documentation confirms pin-compatible replacements including DG3XX, DG4XX, and MAX39X series devices. Verify electrical parameter alignment before substituting these alternative part numbers in existing designs.
