Description

Pericom Semiconductor’s PI5C series of logic circuits are produced
using the Company’s advanced 0.6 micron CMOS technology.

The PI5C16292 and PI5C162292 are 12-bit to 24-bit Mux/Demux
Bus switches designed with a low ON resistance allowing inputs
to be connected directly to outputs.

The PI5C162292 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.

A2 port is not externally connected and, as a result, has an internal
500-ohm pulldown resistor to ground.

Features

• Near-zero propagation delay

•5Ω switches connect inputs to outputs

• Direct bus connection when switches are ON

• Internal 500Ω pull-down on A2 ports

• Ultra-low quiescent power (0.2µA typical)
– Ideally suited for notebook applications

• Industrial operating temperature: –40°C to +85°C

• Make-before-break switching

• Packages available:
– 56-pin 240-mil wide thin plastic TSSOP (A)
– 56-pin 300-mil wide plastic SSOP (V)

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 conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for applicable device.

4. Per TTL driven input (V

= 3.4V, S0 only); A and B pins do not contribute to ICC.

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.

PI5C162292 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.
