Mux/Demux NanoSwitch™
Product Features
Product Description
• Near-Zero propagation delay.
Pericom Semiconductor’s PI3B series of logic circuits are produced
using the company's advanced submicron CMOS technology.
• 5Ω Switches Connect Between Two Ports
• Packages Available :
- 56-pin 240mil Wide Thin Plastic TSSOP(A)
- 56-pin 300mil Wide Plastic SSOP(V)
The PI3B16232 is a 3.3 volt, 16-bit to 32-bit synchronous
switch.
Two select inputs (S0 and S1) control the data flow. A clock (CLK)
and a clock enable (CLKEN) synchronize the device operation.
When CLKEN is high, the bus switch remains in the last clocked
function.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the
lower of the voltages on the two (A,B) pins.
4. This parameter is determined by device characterization but is not production tested.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a + 3.3V supply, IN may be
driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing and Hot-Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC and GND before applying signals to
input/output or control pins.
Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
