PI5C6800C 10-Bit Bus Switch with Precharged Outputs Features Description • Near-Zero propagation delay Pericom’s Semiconductor’s The PI5C6800C is a 10-bit bus switch with low On-State resistance. The bus switch creates no additional propagation delay. 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. • 5Ω switch connection between two ports • Ultra low quiescent power (0.2μA typical) • Ideally suited for Notebook Applications • A port is hot swapable • Packaging (Pb-free & Green available): – 24-pin 150-mil wide QSOP (Q) – 24-pin 173-mil wide TSSOP (L) Block Diagram Pin Configuration 13 23 A1 14 A10 B1 B10 ON ON 1 24 VCC A1 2 23 B1 A2 3 22 B2 A3 4 21 B3 A4 5 20 B4 A5 6 19 B5 A6 7 18 B6 A7 8 17 B7 A8 9 16 B8 A9 10 15 B9 A10 11 14 B10 GND 12 13 BIASV Truth Table(1) Function ON B1 - B10 Connect L A1 - A10 Precharge H BIASV Note: 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. Recommended Operating Conditions Parameters Description Min. Typ.

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. This is the increase in supply current for control input. 3.

For example, given a +5.0V supply, the control input(s) may be driven low to 0V and high to 5.5V. Driving the control input(s) Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying VBIAS and signals to the input/output or control pins.
