Overview
The PS393ESE is a quad single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It features four independent channels within a 16-SOIC package. The device supports a wide supply voltage range, operating on a single supply from 2V to 36V or dual supplies from ±1.0V to ±18V. Key electrical parameters include an on-resistance of 45 Ohms and a leakage current of 100pA. The switch handles a DC current of 30mA with a charge of 3pC. Isolation is rated at -90dB at 1MHz. The component operates within a temperature range of -40°C to +85°C.
Feature Summary
- Quad SPST configuration providing four independent signal paths in a compact surface-mount package.
- Wide supply voltage capability supporting both single and dual power rails for flexible system integration.
- Low leakage current specification ensuring high isolation performance between switched channels.
Applications
- High-speed signal routing in data acquisition systems
- Audio and video signal switching applications
- Programmable gain amplifier configurations
Procurement Notes
Verify the manufacturer designation carefully, as similar part numbers exist across different vendors such as Analog Devices. Confirm that the specific PS393ESE variant matches the required voltage and current specifications for your circuit design. Ensure the package type corresponds to the PCB footprint requirements. Cross-reference the datasheet for any ordering suffixes that may indicate temperature range or packaging variations.
Selection Notes
Select this component when a quad SPST switch with wide voltage tolerance is required. The 45 Ohm on-resistance suits general-purpose analog signal switching rather than precision low-impedance applications. Consider the 100pA leakage current for high-impedance source circuits. The 16-SOIC package offers a balance of pin count and board space efficiency for moderate density designs.
Part Context
The PS393ESE belongs to the family of analog switches designed for general-purpose signal path management. It serves as a discrete solution for multiplexing or demultiplexing signals in electronic circuits. The device complements other interface components by providing reliable mechanical-free switching capabilities. Its design focuses on balancing speed, isolation, and voltage handling for industrial and consumer electronics.
Replacement Considerations
The AS393 is a documented alternative from Diodes Incorporated offering wider supply voltage ranges up to ±18V dual supplies. Verify pin compatibility and on-resistance differences when substituting. Other quad SPST switches may require level shifting or voltage rail adjustments to match the PS393ESE operating conditions.
