PI5C6800
10-Bit BusSwitch with Precharged Outputs for Live Insertion
Product Features
Near zero propagation delay 5 Ohm switch connection between two ports Ultra low quiescent power (0.2µA typ.) Ideally suited for Notebook Applications Outputs are precharged by bias voltage to minimize signal distortion during live insertion Packages options: 24-pin 150-mil wide plastic QSOP (Q) 24-pin 173-mil wide TSSOP (L)
Product Description
Pericoms Semiconductors PI5C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI5C6800 is a 10-bit bus switch with low ON-state resistance. The bus switch creates no additional propagation delay. The device also precharges the B port to a user-selectable bias voltage (BIASV) to minimize live-insertion noise. 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 10-k resistor.

(Above which the useful life may be impaired. For user guidelines, not tested.) Storage Temperature ........... 65°C to +150°C Supply Voltage Range ..... 0.5V to +7V DC Input Voltage(1) .... 0.5V to +7V Input Clamp Current, II K (V1<0) ......... 50mA DC Output Current ..... 120mA Power Dissipation(2) .. 0.5W
Note: S t r e s s e s greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and f u n c t i o n a l operation of the device at these or any other conditions above those indicated in the o p e r a t i o n a l sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
Notes: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperatue of 150°C and a board trace length of 750 mils.

Notes: * 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. E This is the increase in supply current for each input that is at the specified TTL voltage level rather the VCC or GND. = All typical values are at VCC = 5V, TA = 25°C.
