Overview
The PI3A3159ZCEX is a single-pole double-throw (SPDT) CMOS analog switch manufactured by Diodes Incorporated. It operates within a supply voltage range of +1.5V to +3.6V and features an on-resistance of 0.4Ω at a 2.7V supply. The device provides rail-to-rail switching, fast switching speeds with a maximum turn-on time of 20ns at 3.3V, and high off-isolation of -27dB at 100kHz. It includes -41dB crosstalk rejection and operates across an extended industrial temperature range from -40°C to +85°C.
Feature Summary
- Single-pole double-throw (SPDT) architecture for signal routing
- Low on-resistance of 0.4Ω at 2.7V supply voltage
- High off-isolation and crosstalk rejection capabilities
- Rail-to-rail switching throughout the signal range
Applications
- Cell phones
- PDAs
- Portable instrumentation
- Battery-powered communications
- Computer peripherals
Procurement Notes
Verify component authenticity through authorized channels. Confirm package integrity upon receipt. Ensure storage conditions remain within specified limits. Check for physical damage before installation. Validate part markings against official documentation.
Selection Notes
Evaluate supply voltage compatibility with system requirements. Consider on-resistance impact on signal integrity. Assess thermal performance within operating temperature range. Verify logic input levels match control signals. Review packaging options for assembly constraints.
Part Context
This component belongs to the PI3A3159 series of SPDT analog switches. It serves as a low-voltage replacement for the PI5A3159 model. The device utilizes CMOS technology suitable for bus and analog applications. It is designed for compact portable electronic systems requiring efficient signal switching.
Replacement Considerations
The PI5A3159 is identified as a predecessor model replaced by this component. Verify pinout compatibility when substituting. Confirm electrical specifications meet original design requirements. Check package dimensions for mechanical fit.
