PI3B16232

PI3B16232
3.3V, Synchronous 16-Bit to 32-Bit FET
Mux/DeMux NanoSwitch™
Features
Description
• Near-Zero propagation delay.
The PI3B16232 is a 3.3 volt, 16-bit
switch.
• 5-ohm Switches Connect Between Two Ports
to 32-bit synchronous
• Packaging (Pb-free & Green available):
– 56-pin 240mil Wide Thin Plastic TSSOP (A)
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.

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.
