PI3C16215
3.3V, 2-Port, 20-Bit Bus Switch with Precharged Outputs for Live Insertion
Product Features
Near zero propagation delay 5-ohm switch connection between two ports High Bandwidth (>200 MHz) Rail-to-Rail 3.3V Switching Outputs are precharged by bias voltage to minimize signal distortion during live insertion 5V I/O Tolerant Package options: 48-pin 150 mil wide plastic BQSOP (B) 48-pin 240 mil wide plastic TSSOP (A)
Product Description
Pericom Semiconductors PI3C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI3C16215 is a 20-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 (OE) input. When OE is LOW, the switch is on and port A is connnected to port B. When OE 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.

Note: 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.
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 150C 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 = 25C.

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(R) 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 input/output or control pins.
