PI3V312ZHEX

Analog Switches - Special Purpose Overview

The PI3V312ZHEX is a 4-port, 2:1 Multiplexer/Demultiplexer with 3-state outputs manufactured by Diodes Incorporated. It operates on a single 3.3V supply (also supporting 2.5V) and features a high signal passing bandwidth of 500MHz. The device provides near-zero propagation delay and low on-resistance ranging from 4Ω to 8Ω depending on voltage conditions. It includes 2KV ESD protection and latch-up performance exceeding 250mA per JESD17 standards. The component is housed in a 20-contact TQFN package and supports an industrial operating temperature range from -40°C to +85°C.

• Provides exceptionally low crosstalk and off-isolation characteristics

Analog Switches - Special Purpose Applications

• Video signal switching
• Datacom applications
• Telecom applications

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ZHE corresponds to the 20-contact TQFN package configuration. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Ensure that the selected packaging variant matches the required surface-mount assembly specifications for the target application design.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-bandwidth video signal routing with minimal propagation delay. Verify that the system power supply aligns with the specified 2.5V or 3.3V operational ranges. Consider the 20-contact TQFN footprint constraints during PCB layout planning to ensure proper thermal dissipation and mechanical stability for the intended deployment environment.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3V312 family of low on-resistance, high-bandwidth video switches. The ZHE suffix specifically identifies the 20-contact TQFN package variant within the broader product line. Other variants in this series include QSOP and TSSOP packages, offering flexibility for different board space requirements while maintaining identical electrical performance characteristics across all package types.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements must maintain the 4-channel 2:1 mux/demux architecture and 20-TQFN form factor. Verify that substitute components support the same 500MHz bandwidth and 3.3V supply operation. Ensure pinout compatibility to avoid redesigning the host circuit board when integrating alternative switch ICs into existing designs.
