pi3usb14 Pericom Semiconductor Corporation, pi3usb14 Datasheet - Page 7

• Manufacturer Part Number: pi3usb14
• Description: 3.3v, 2-channel, 4 1 Mux Usb 2.0 Switch
• Manufacturer: Pericom Semiconductor Corporation

Packaging Mechanical: 16-pin QSOP (Q)
Applications Information
Logic Inputs
The logic control inputs can be driven upto 3.6Vregardless of the supply voltage. For example, given a +3.3V supply, EN maybe
driven LOW to 0V and HIGH to 3.6V. Driving EN Rail-to-Rail
Power Supply-Sequencing
Proper power supply sequencing is recommended for all CMOS devices. Always apply V
output or control pins.
Hot Insertion
For Datacom and Telecom applications that have ten or more volts passing through the backplane, a high voltage from the power
supply may be seen at the device input pins during hot insertion. The PI3CHxx devices have maximum limits of 6V and 120mA for
20ns. If the power is higher or applied for a longer time or repeatedly reaches the maximum limits, the devices can be damaged.
