PI5C6800
10-Bit Bus Switch with
Precharged Outputs
Features
• Near-Zero propagation delay
Description
Pericom’s Semiconductor’s PI5C6800 is a 10-bit bus switch with
low On-State resistance. The bus switch creates no additional
propagation delay.
• 5Ω switch connection between two ports
• Ultra-low quiescent power (0.2μA typical)
• Ideally suited for notebook applications
• A port is hot swapable
The switch is turned on by a single enable (ON) input. When ON
is LOW, the switch is on and port A is connnected to port B. When
ON is HIGH, the switch between port A and port B is open and
the B port is precharged to BIASV through the equivalent of a
10k-ohm resistor.
• Packaging (Pb-free & Green available):
– 24-pin 150-mil wide QSOP (Q)
– 24-pin 173-mil wide TSSOP (L)

Notes:
1. 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 extended periods may affect reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. The maximum package power dissipation is calculated using a junction temperatue of 150°C and a board trace length of 750 mils.

Notes:
1. Measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-State resistance is determined by
the lower of the voltages of the two (A or B) terminals.
2. All typical values are at VCC = 5V, TA = 25°C.

Notes:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical On-State resis-
tance of the switch and a load capacitance of 50pF, when driven by an ideal voltage source (zero output impedance).

• CL includes probe and jig capacitance.
• Waveform 1 is for an output with internal conditions such that the output is LOW except when disabled by the output control.
• Waveform 2 is for an output with internal conditions such that the output is HIGH except when disabled by the output control.
• All input pulses are supplied by generators having the following characteristics: PRR < 10MHz, ZO = 50ꢀ, tr ≤ 2.5ns, tf ≤ 2.5ns.
• The outputs are measured one at a time with one transition per measurement.
• tPLZ and tPHZ are the same as tdis

Applications Information
Logic Inputs
The logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a +5.0V supply, control
®
inputs may be driven low to 0V and high to 5.5V. Driving control inputs Rail-to-Rail minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V before applying signals to the input/
CC
output or control pins.
