Product Description
Pericom Semiconductors PI3C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI3C6800 is a 10-bit bus switch with low on-state resistance. The bus switch creates no additional propagation delay. To minimize live-insertion noise, the device also precharges the B port to a userselectable bias voltage (BIASV). 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.

Absolute Maximum Ratings Over Free-Air Temperature Range*
(Above which the useful life may be impaired. For user guidelines, not tested.) Storage Temperature ....... 65°C to +150°C Note: Stresses greater than those listed under MAXIMUM RATINGS Supply Voltage Range ......... 0.5V to 4.6V may cause permanent damage to the device. This is a stress rating DC Input Voltage(1) ..... 0.5V to +7V only and functional operation of the device at these or any other Input Clamp Current, II K (V1< 0) .... 50mA conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum DC Output Current ......... 120 mA rating conditions for extended periods may affect reliability. (2) Power Dissipation .......... 0.5W Notes: 1. Input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. 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. This is the increase in supply current for control input. All typical values are at VCC = 3.3V, TA = 25°C.
