PI5C32384 (25Ω)

10-Bit, 2-Port BusSwitch

Product Features:

• Near-zero propagation delay

Product Description:

Pericom Semiconductor’s PI5C series of logic circuits are pro-

duced in the Company’s advanced sub-micron CMOS technology,

achieving industry performance.

• Low noise, 25Ω version (PI5C32384)

• 5Ω switches connect inputs to outputs (PI5C3384)

•

Direct bus connection when switches are ON

The PI5C3384, PI5C3384C, and PI5C32384 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

propagationaldelayoradditionalgroundbouncenoise.Theswitches

are turned ON by the Bus Enable (BE) input signal. Two bus enable

signals are provided, one for each of the upper and lower five bits

ofthetwo10-bitbuses. ThePI5C32384isdesignedwithaninternal

25Ω resistor reducing noise reflection in high-speed applications.

Ultra-low quiescent power (0.2 µA typical)

– Ideally suited for notebook 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 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.

5. This parameter is determined by device characterization but is not production tested.

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 (V^IN= 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 0.25 ns for 50 pF 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.
