Product Features
Product Description
•
•
•
•
Pericom Semiconductor’s PI3C series of Bus Switch circuits are
produced using the Company’s advanced submicron CMOS
technology, achieving industry leading speed.
The PI3C16210 is configured as a 20-bit, 2-port bus switch designed
with a low ON resistance (5 Ohm) allowing inputs to be connected
directly to outputs. The bus switch creates no additional
propagational delay or additional ground bounce noise. The switch
is turned ON by the Bus Enable (xOE) input signal.
Near-zero propagation delay
5-Ohm switch connects inputs to outputs
Direct bus connection when switch is ON
32X384 function with flow through pinout makes
board layout easier
• Ultra-low quiescent power (0.2mA typical)
– ideally suited for notebook applications
• Industrial operating temperature: –40°C to +85°C
• Packages available:
– 48-pin 173-mil wide plastic TVSOP (K)
– 48-pin 240-mil wide plastic TSSOP (A)

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. 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.
5. This parameter is determined by device characterization but is not production tested.

Notes:
1. See test circuit and waveforms.
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.
