PI3CH1012QEX

Analog Switches - Special Purpose Overview

The PI3CH1012QEX is a 10-bit bus switch manufactured by Diodes Incorporated, designed for high-bandwidth applications and hot plug operations. It operates with supply voltages of 1.8V, 2.5V, or 3.3V and features two independent enable inputs (EN, EN). The device utilizes a 24-pin QSOP package. Key electrical parameters include a maximum on-resistance ranging from 6 to 25 Ohms depending on voltage and current conditions, a quiescent power supply current of up to 0.5 mA at 3.6V, and a -3dB bandwidth of 500 MHz. Propagation delay is guaranteed at a maximum of 0.3 ns, while enable and disable times vary between 1.5 ns and 25.0 ns based on the operating voltage range.

Analog Switches - Special Purpose Feature Summary

• Dual-enable architecture providing flexible control over the ten bidirectional data channels.
• High-bandwidth capability supporting signal integrity in demanding digital interfaces.
• Designed specifically for hot insertion environments to manage transient conditions safely.

Analog Switches - Special Purpose Applications

• Hot plug peripheral connections

• Data acquisition equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the QEX designation corresponds to the required 24-pin QSOP package and tape/reel packaging format. Ensure compliance with RoHS directives and lead-free manufacturing standards as specified in the component datasheet.

Analog Switches - Special Purpose Selection Notes

Select this component when a 10-channel bus switch with dual enable pins is required for low-voltage logic levels. Evaluate the on-resistance specifications relative to the target supply voltage and load current to ensure acceptable signal attenuation. Consider the 500 MHz bandwidth for high-speed data lines and verify thermal dissipation requirements for the chosen package style.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3CH series of bus switches from Diodes Incorporated. The 'Q' suffix indicates the 24-pin QSOP package variant, while the 'EX' suffix denotes tape and reel packaging. This specific configuration distinguishes it from other pinout or packaging options within the broader product family.

Analog Switches - Special Purpose Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the 10-bit channel count, dual-enable functionality, and compatible voltage ranges.

Analog Switches - Special Purpose FAQ

What is the maximum propagation delay for the PI3CH1012?

The maximum propagation delay is guaranteed at 0.3 ns across all specified operating voltage ranges.

How does the on-resistance vary with supply voltage?

On-resistance increases as the supply voltage decreases; for example, at 1.8V it can reach up to 25 Ohms, whereas at 3.3V it is typically lower, around 6 to 8 Ohms under similar current loads.

Is the device suitable for hot plug applications?

Yes, the datasheet explicitly lists hot plug as a primary application feature for this component.
