Product Description
Pericom Semiconductor’s PI3B series of BusSwitch circuits are
produced in the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The PI3B16210 is configured as 3.3 volt 20-bit, 2-port bus
switches designed with a low ON resistance (5) allowing inputs
to be connected directly to outputs. The bus switch creates no
additional propagational delay or additional ground bounce noise.
The switches are turned ON by the Bus Enable (xOE) input signal.
The PI3B162210 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.

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, +25°C ambient.
3. Per TTL driven input (control inputs only); A and B pins do not contribute to Icc.
4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified
frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is
guaranteed by design.

Notes:
1. See test circuit and wave forms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load
capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much
smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational 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.
