Product Description

Pericom Semiconductors PI5C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry leading performance.

The PI5C3383 and PI5C32383 are 5-bit, 4-port bus switch with
exchange 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, and the Bus
Exchange (BX) input signal offers nibble swapping of the AB and
CD pairs of signals. This exchange configuration allows byte
swapping of buses in systems. It can also be used as a quad
2-to-1 multiplexer and to create low delay barrel shifters, etc. The
PI5C32383 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 = 5.0V, 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 AB and CD pin at indicated current through the switch. ON resistance is determined by
the lower of the voltages on the two (A or B, C or D) pins.

Notes:

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 0.25\ns 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.

Applications

Logic Inputs

The logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a 5.0V supply, the control
or select pins may be driven low to 0V and high to 5.5V. Driving the control or select pins Rail-toRail minimizes power
consumption.

Power-Supply Sequencing

Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/
output or control pins.
