PI5C3384
PI5C3384C
10-Bit, 2-Port Bus Switch
Features:
Description:
• Near-Zero propagation delay
Pericom Semiconductor’s PI5C3384 and PI5C3384C are 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 (BEx) input
signals. Two bus enable signals are provided, one for each of the
upper and lower five bits of the two 10-bit buses.
• 5Ω 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):
– 24-pin 150-mil wide plastic QSOP (Q)
– 24-pin 300-mil wide plastic SOIC (S)
– 24-pin 173-mil wide plastic TSSOP (L)

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 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.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, 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.
