ADG3247:  2.5 V/3.3 V, 16 BIT (DUAL 8 BIT) , 2 PORT LEVEL TRANSLATOR, BUS SWITCH

The ADG3247 is a 2.5 V or 3.3 V 16 Bit (Dual 8 Bit), 2 port digital switch. It is designed on our low voltage CMOS process which provides low power dissipation yet gives high switching speed and very low on resistance allowing inputs to be connected to the outputs without additional propagation delay or generating additional ground bounce noise.

ADG3247:  2.5 V/3.3 V, 16 Bit (Dual 8 Bit) , 2 Port Level Translator, Bus Switch

Product Description

The ADG3247 is a 2.5 V or 3.3 V 16 Bit (Dual 8 Bit), 2 port digital switch. It is designed on our low voltage CMOS process which provides low power dissipation yet gives high switching speed and very low on resistance allowing inputs to be connected to the outputs without additional propagation delay or generating additional ground bounce noise.

The switches are enabled by means of the Bus Enable, () input signal. These digital switches allow bi-directional signals 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 3.3V inputs to 2.5V outputs is allowed. Similarly, if the device is operated from a 2.5 V supply and 2.5 V inputs are applied, the device will translate the outputs to 1.8 V. In addition to this, a level translating select pin () is included. When is low, VCC is reduced internally allowing for level translation between 3.3V inputs and 1.8V outputs. This makes the device suited to applications requiring level translation between different supplies, such as converter to DSP interfacing.
