PI5C33X257
12-Channel, 2:1 Mux/DeMux Bus Switch
Features
• Near-Zero propagation delay
Description
The PI5C33X257 is a 12-channel, 2:1 multiplexer/demultiplexer
with three-state outputs. Inputs can be connected to outputs with
low on resistance (5-ohm) with no additional ground bounce noise
or propagation delay.
• 5-ohm switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.2µA typical)
– Ideally suited for notebook applications
• Packaging (Pb-free & Green Available):
– 48-pin 150 mil wide plastic BQSOP (B)

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 I and Y pin at indicated current through the switch. ON resistance is determined by the lower of the volt-
ages on the two (I,Y) pins.

2. Typical values are at Vcc = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, control inputs only); I and Y 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 I and Y 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.
