PI3A212ZLEX

Analog Switches - Special Purpose Overview

The PI3A212ZLEX is a dual single-pole double-throw (SPDT) analog switch manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7V to 4.2V and supports rail-to-rail signal ranges. The device features an on-resistance of 0.6Ω at +2.7V, with a maximum of 0.8Ω. Key electrical parameters include off-isolation of -75dB at 100kHz, crosstalk rejection of -90dB at 100kHz, and a 3dB bandwidth of 60MHz. Turn-on time is typically 25ns, while turn-off time is typically 10ns. The component utilizes CMOS technology and is housed in a 10-contact TQFN package.

Analog Switches - Special Purpose Feature Summary

• Break-before-make switching mechanism prevents simultaneous switch enablement to eliminate signal disruption during transitions.
• High off-isolation and crosstalk rejection capabilities reduce signal distortion for bus and analog applications.
• Rail-to-rail signal range accommodates wide input/output voltage swings relative to the power supply.

Analog Switches - Special Purpose Applications

• Speaker headset switching
• Audio and video signal routing
• Power routing
• Relay replacement

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer designation as Diodes Incorporated, noting the original design origin from Pericom Semiconductor. Confirm the specific ZL suffix indicates the 10-contact TQFN package type. Ensure compliance with RoHS standards and verify the lead-free and green material specifications required for the intended assembly process.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring low on-resistance and high off-isolation in portable electronics. Verify that the operating temperature range of –40°C to +85°C meets environmental requirements. Ensure the control input logic levels are compatible with the system voltage and that unused inputs are properly grounded to prevent floating states.

Analog Switches - Special Purpose FAQ

What is the function of the break-before-make switching feature?

It ensures that both switches are not enabled simultaneously, thereby eliminating signal disruption during switching operations.

How does the device handle unused inputs?

Unused inputs must be held HIGH or LOW and must not float; specifically, unused NC or NO ports should be grounded.

What is the typical charge injection value?

The typical charge injection is 55 pC under specified test conditions.
