The ADG3243 is a 2.5 V or 3.3 V, 2-bit, 2-portDigital switch, each channel is independently controlled. It is manufactured on a low-voltage CMOS process and 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 (
The input signal is enabled. When switched on, the digital switch switches bidirectional signals. 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. This makes the device suitable for applications that require level translation between different power supplies, such as interfacing converters with DSPs or microcontrollers.
