PI5V331QE

Analog Switches - Special Purpose Overview

The PI5V331QE is a dual 4-channel multiplexer/demultiplexer manufactured by Diodes Incorporated in a 16-pin QSOP package. It operates on a single +5.0V supply with a voltage range of 4.75V to 5.25V. The device features a typical on-resistance of 3Ω and a maximum of 10Ω, alongside a -3dB bandwidth of 150MHz. Switching times are limited to 5ns for both turn-on and turn-off. It supports an analog signal range of 0V to 2.0V and provides high current capability with a short circuit current of 100mA. Quiescent power consumption is typically 0.1μA.

Analog Switches - Special Purpose Feature Summary

• Dual 4-channel configuration designed for S-Video or composite video switching applications
• High-performance bidirectional switching with low on-resistance and wide bandwidth
• Ultra-low quiescent power consumption suitable for battery-operated systems
• Functionally equivalent to the QS4A210 component

Analog Switches - Special Purpose Applications

• S-Video switching
• Composite video source switching
• RAMDAC current output driving
• Voltage output composite video source connection

Analog Switches - Special Purpose Procurement Notes

Verify the ordering suffix 'E' confirms Pb-free and Green packaging status as specified in the datasheet. Confirm the 'Q' suffix corresponds to the 16-pin 150-mil wide plastic QSOP package type. Ensure compatibility with single +5.0V supply requirements and check that the application environment remains within the -40°C to +85°C operating temperature range.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual 4-channel mux/demux is required for video signal routing. The 150MHz bandwidth and 3Ω on-resistance make it suitable for maintaining signal integrity in composite video paths. Consider the 100mA short circuit current capability if driving heavy loads. Verify that the 16-pin QSOP footprint fits the PCB layout constraints.

Analog Switches - Special Purpose Part Context

The PI5V331 is part of Pericom Semiconductor's (now Diodes Incorporated) low on-resistance wideband video switch family. It serves as a direct functional replacement for the QS4A210. The device integrates decoder logic for channel selection via IN0 and IN1 pins, enabling efficient control of four analog inputs per channel using minimal digital control lines.

Analog Switches - Special Purpose Replacement Considerations

The datasheet explicitly states the PI5V331 is functionally equivalent to the QS4A210. No other substitute part numbers are documented in the provided source material.
