The ADG3246 is a 2.5 V or 3.3 V, 10-bit, 2-portDigital switchManufactured on a low-voltage CMOS process, it features low power consumption, high switching speed, and very low on-resistance. The input can be connected to the output without causing additional propagation delay or additional ground bounce noise.
These switches are enabled via a bus (
) input signal enabled. Under the on-condition, theDigital switchBidirectional signals can be switched. Under the disconnected condition, the signal level that reaches the supply voltage is prevented. This device is ideal for applications requiring level shifting. When operating from a 3.3 V supply, a 3.3 V input level can be converted to a 2.5 V output level. Similarly, if the device operates from a 2.5 V supply and a 2.5 V input is applied, the device is converted to a 1.8 V output. In addition, the device contains a level shifting select pin (
), when When low, VCC Internal reduction allows the 3.3 V input level to be converted to a 1.8 V output level. This makes the device suitable for applications that require level shifting between different power supplies, such as interfacing converters with DSPs.
