Overview
The PI3A223ZMEX is a dual SPDT analog switch manufactured by Diodes Incorporated, housed in a 10-UQFN (1.8x1.4mm) package. It operates on a single supply voltage ranging from 1.65V to 4.2V. The device features an on-resistance of up to 750 milliohms at 4.2V and 900 milliohms at 3.0V. Key electrical parameters include a 3dB bandwidth of 84MHz at 4.2V, channel-to-channel crosstalk of -90dB at 10MHz, and charge injection of 50pC. The component supports a continuous current of ±300mA and functions within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Dual Single-Pole Double-Throw (SPDT) switching architecture
- Low on-resistance for minimal signal attenuation
- High isolation and low crosstalk performance
- Compatible with low-voltage digital logic control
Applications
- Portable multimedia devices
- LCD panel biasing circuits
- Video signal routing
- Audio signal switching
Procurement Notes
Verify the specific ordering suffix 'ZMEX' against the manufacturer's datasheet to confirm the 10-UQFN package type and tape-and-reel packaging configuration. Ensure that the procurement documentation explicitly states compliance with RoHS 3 directives and confirms the lead-free status required for modern assembly processes.
Selection Notes
Select this component when a dual-channel analog switch is required for low-voltage applications between 1.8V and 4.2V. Consider the 750 milliohm maximum on-resistance and 84MHz bandwidth limits relative to the target signal frequency. Verify that the 10-UQFN footprint matches the PCB layout constraints and that the thermal characteristics are suitable for the intended operating environment.
Part Context
The PI3A223 belongs to Diodes Incorporated's family of small plastic package analog switches. This series is designed for portable electronics where space efficiency and low power consumption are critical. The ZMEX designation specifically identifies the ultra-thin quad flat no-lead package variant optimized for surface-mount technology.
Replacement Considerations
Consult official substitution lists for verified alternatives. Generic cross-references may not match the specific pinout or electrical tolerances of the PI3A223ZMEX.
