Product Description

Pericom Semiconductors PI3C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry performance.

The PI3C3384, and PI3C32384 are 2.5V or 3.3Volt, high bandwidth
10-bit, 2-port bus switches designed with a low ON resistance
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 (BE)
input signal. Two bus enable signals are provided, one for each of
the upper and lower five bits of the two 10-bit buses. The
PI3C32384 is designed with an internal 25Ω resistor reducing
noise reflection in high-speed applications.

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. 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 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.
