Description
Pericom Semiconductor’s PI3B16210 is configured as a 3.3 volt
20-bit, 2-port bus switch designed with a low On-Resistance
(5-ohms) allowing inputs to be connected directly to outputs.
The bus switch creates no additional propagational delay or
additional ground bounce noise. Switches are turned ON by the
Bus Enable (xOE) input signal.

Notes:
1. This parameter is guaranteed but not tested on Propagation Delays.
2. The bus switch contributes no propogational delay other than the On-Resistance of the switch and load capacitance. The time con-
stant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much swmaller than the rise/fall times of
typical. driving signals, it adds very little propogational delay to the system. Propogatioonal delay of the bus switch when used in a
system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6 regardless of the supply voltage. For example, given a +3.3V
suppply, 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 V
CC
and GND before
applying signals to input/output or control pins.
