DG419CY+T

The DG419CY+T is a precision, monolithic, quad analog switch designed for 4-channel analog signal multiplexing and demultiplexing. It is part of the DG419 series of analog switches from Intersil and can be used as a multiplexer, a demultiplexer, or as an analog crossbar, depending on the application. The DG419CY+T is an ideal choice for analog multiplexing or demultiplexing applications and is suitable for use in a wide range of applications such as industrial, medical, and consumer electronics.

This part of the DG419 series of analog switches is an 8 to 1 multiplexer/demultiplexer; it includes four channels and is rated for use with a maximum voltage of 10V DC. The DG419CY+T has low on-resistance, low power dissipation, wide signal-switching bandwidth, and high-voltage rail handling capability which makes it suitable for a variety of applications. This part also has a very low input capacitance, fast switching speed and low pulse distortion, which makes it useful for signal multiplexing and demultiplexing applications.

The DG419CY+T operates by applying a logic input signal to select which signal from the four inputs is switched to the output. The four logic inputs control the gate voltages of the MOS switches and each of the four switches can independently be enabled or disabled. When enabled, the switch is closed and a signal is applied to the output. When disabled, the switch is open and no signal is present at the output. The control logic inputs can be either positive or negative going.

The DG419CY+T also features on-chip charge pump drivers that supply voltage to the selection logic. The logic selection is latched and the logic inputs can be changed without affecting the selection. This part is also available in a small SO-8 package, making it suitable for use in portable equipment. The DG419CY+T is also rated for operating temperatures from -40°C to +125°C and is RoHS compliant.

In conclusion, the DG419CY+T is an ideal choice for analog multiplexing or demultiplexing applications and can be used in a wide range of applications. This part includes four channels, low on-resistance, low power consumption, wide signal-switching bandwidth and high-voltage rail handling capability. It also has a low input capacitance, fast switching speed and low pulse distortion, which makes it a suitable analog multiplexing or demultiplexing solution. The part is also available in a small SO-8 package and is rated for temperature operation from -40°C to +125°C.
