Product Description

Pericom Semiconductors PI3C series of logic circuits are produced using the Companys 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-kΩ resistor.

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.

Note:

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

Applications Information

Logic Inputs

The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, IN may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.

Power-Supply Sequencing

Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying V input/output or control pins.
