The HMC955LC4BTR is a silicon monolithic IC that belongs to a group of analog switch products known as Special Purpose. This type of IC utilizes a CMOS process featuring very low capacitance and on resistance and low power dissipation, making it ideal for handling signals from high speed serial data and analog communication. This particular IC can switch 1.5GHz of differential signals, blocking DC and AC signals, is typically used in applications such as transmitters, receivers, attenuators and other signal routing applications.

The basic design of the HMC955LC4BTR is an integrated circuit that can switch between two or more channels. The circuit is composed of four CMOS gates arranged in a specific configuration to create a momentary power switch. This switch can control two analog signals and two control lines. The first two control lines are used to select the active channel, while the second two control lines are used to transmit the signal from one channel to the other. The IC has a total on resistance of just 25 milliohms and a total off resistance of 80 milliohms. This is ideal for minimizing power dissipation when switching high impedance analog signals.

Two common applications for this IC are signal routing and signal conditioning. For signal routing, the HMC955LC4BTR can be used to multiplex two or more signal sources onto a single signal line. This is done by using two control lines to select the active signal channel and two control lines to transmit the signal from one channel to the other. An example of this application is mixing multiple audio signals into a single signal. Another application is signal conditioning, wherein the HMC955LC4BTR can be used to condition a signal before it is routed. An example of this is using the IC to attenuate high frequency signals or to amplify weak signals before switching to the active channel.

In summary, the HMC955LC4BTR is a silicon monolithic IC designed for signal routing and signal conditioning applications. It utilizes a CMOS process featuring very low capacitance and on-resistance and low power dissipation, making it ideal for handling signals from high speed serial data and analog communication. It has a total on resistance of just 25 milliohms and a total off resistance of 80 milliohms, allowing for minimized power dissipation when switching high impedance analog signals. This type of IC is typically used in applications such as transmitters, receivers, attenuators, and other signal routing applications.
