2.5V/3.3V，2位共同控制電平轉(zhuǎn)換器總線開關(guān)ADG3242數(shù)據(jù)表

　　The ADG3242 is a 2.5 V or 3.3 V， 2-bit， 2-port， common control digital switch. It is designed on a low voltage CMOS process， and provides low power dissipation， yet gives high switching speed and very low on resistance. This allows the inputs to be connected to the outputs without additional propagation delay or generating additional ground bounce noise.These switches are enabled by means of a common bus enable （BE） input signal. This digital switch allows a bidirectional signal to be switched when on. In the off condition， signal levels up to the supplies are blocked.This device is ideal for applications requiring level translation. When operated from a 3.3 V supply， level translation from 3.3 V inputs to 2.5 V outputs is allowed. Similarly， if the device is oper-ated from a 2.5 V supply and 2.5 V inputs are applied， the device translates the outputs to 1.8 V. In addition， a level translating select pin （SEL） is included. When SEL is low， VCC is reduced internally， allowing for level translation between 3.3 V inputs and 1.8 V outputs. This makes the device suitable for applications requiring level translation between different supplies， such as converter to DSP/microcontroller interfacing.
