Description
Pericom Semiconductor’s PI3B16233 is a 16-bit to 32-bit mux/demux
switch. This device can be used for memory bank interleaving. The
PI3B16233 can be used as two 8-bit to 16-bit multiplexers or as one
16-bit to 32-bit multiplexer.
Two select inputs (SEL1 and SEL2) control the data flow. When the
TEST inputs are asserted HIGH, the A port is connected to both the
B1 and the B2 ports.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
CC
= 3.3V, T
A
= 25°C ambient and maximum loading.
3. 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.
4. This parameter is determined by device characterization but is not production tested.

Note:
Stresses greater than those listed under MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may
affect reliability.

Power Supply Characteristics
Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V
CC
= 3.3V, +25°C ambient.
3. Per TTL driven input (control inputs only); A and B pins do not contribute to I
CC
.
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.
Switching Characteristics over Operating Range
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.
