ADG3245BRUZ

Price range: $2.05 - $3.03

The ADG3245 is a 2.5 V or 3.3 V, 8-bit, 2-port digital switch.It is designed on Analog Devices’ low voltage CMOS process,which provides low power dissipation yet gives high switchingspeed and very low on resistance, allowing inputs to be connectedto outputs without additional propagation delay or generatingadditional ground bounce noise.The switches are enabled by means of the bus enable (BE) inputsignal. These digital switches allow bidirectional signals to beswitched when ON. In the OFF condition, signal levels up tothe 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 Vinputs to 2.5 V outputs is allowed. Similarly, if the device isoperated from a 2.5 V supply and 2.5 V inputs are applied, thedevice will translate the outputs to 1.8 V. In addition to this, alevel translating select pin (SEL) is included. When SEL is low,VCC is reduced internally, allowing for level translation between3.3 V inputs and 1.8 V outputs. This makes the device suited toapplications requiring level translation between different supplies,such as converter to DSP/microcontroller interfacing.APPLICATIONS 3.3 V to 1.8 V voltage translation 3.3 V to 2.5 V voltage translation 2.5 V to 1.8 V voltage translation Bus switching Bus isolation Hot swap Hot plug Analog switch applicationsPRODUCT HIGHLIGHTS 3.3 V or 2.5 V supply operation Extremely low propagation delay through switch 4.5 Ω switches connect inputs to outputs Level/voltage translation 20-lead TSSOP and LFCSP (4 mm × 4 mm) packages
