资 源 简 介
The ADG3241 is a 2.5 V or 3.3 V single digital switch. It is designed on a low voltage CMOS process that provides low power dissipaTIon yet gives high switching speed and very low on resistance. This allows the input to be connected to the output without addiTIonal propagaTIon delay or generaTIng additional ground bounce noise. The switch is enabled by means of the 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 operated from a 2.5 V supply and 2.5 V inputs are applied， the device translates the outputs to 1.8 V. In addition to this， 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 suited to applications requiring level translation between different supplies， such as converter to DSP/microcontroller interfacing.
