PI3B16292
Description
Pericom Semiconductor's PI3B series of logic circuits are produced
using the Company's advanced submicron CMOS technology.
The PI3B16292 is a 3.3 volt, 12-bit to 24-bit Mux/Demux Bus switches
designed with a low On-resistance allowing inputs to be connected
directly to outputs.
A2 port is not externally connected and, as a result, has an internal
500 ohm pulldown resistor to ground.

Note:
Stresses greater than those listed under MAXIMUM
RATINGS 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 ex-
tended periods may affect reliability.
Capacitance
(T
A
= 25C, f = 1 MHz)
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, T
A
= 25C 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.

Power Supply Characteristics
Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for applicable device.
2. Typical values are at V
CC
= 3.3V, +25C ambient.
3. This is the increase in supply current for S0
at the specified TTL voltage level rather than V
CC
or GND.
4. Per driven input ( S0 only); A and B pins do not contribute to I
CC
.
5. 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.
3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and 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 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.
4. Applies to t
PLZ
and t
PZL

Ordering Information
Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of
the supply voltage. For example, given a + 3.3V supply, IN may
be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail
minimizes power consumption.
Power-Supply Sequencing and Hot-Plug Information
Proper power-supply sequencing is recommended for all CMOS
devices. Always apply V
CC
and GND before applying signals to
input/output or control pins.
Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
