The ADG3241 is a 2.5 V or 3.3 V, single digital switch. It is designed on a low voltage CMOS process, which 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. WhenSELis low, VCCis 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.PRODUCT HIGHLIGHTS3.3 V or 2.5 V supply operation.Extremely low propagation delay through switch.4.5 Ω switches connect inputs to outputs.Level and voltage translation.Tiny, SC70 package and SOT-66 package.APPLICATIONS3.3 V to 1.8 V voltage translation3.3 V to 2.5 V voltage translation2.5 V to 1.8 V voltage translationBus switchingBus isolationHot swapHot plugAnalog switch applications
