The ISL81485IBZ-T is a low-power, high-bandwidth "Tri-state differential receiver/transmitter pair" designed for high-speed differential data transmission in communication systems. It is suitable for interface applications where the differential voltage levels are between 0.5V and 2V. The device is available in an 8-lead SOIC package.

The ISL81485IBZ-T consists of two independent, low-power, high-bandwidth channels that are identical in operation. Each of the channels supports a different type of data transmission, with a maximum data rate of 25 Mbps. The first channel is a differential transistor-transistor-logic (TTL) receiver/transmitter, while the second channel is a differential complementary metal-oxide-semiconductor (CMOS) receiver/transmitter. Each of the channels can be enabled or disabled independently, allowing multiple data sources to be connected to the board, depending on the application. The device also has an analog on/off control pin for use in switching the power mode between ‘active’ and ‘standby’.

The receiver portion of the ISL81485IBZ-T is capable of receiving differential voltage signals from 0.5V to 2V. This is done by an integrated, adjustable input offset voltage amplifier. The receiver is also capable of amplifying the input signal, filtering out noise, and providing high noise immunity. The separate transmitters of the ISL81485IBZ-T provide differential current drive of up to 20 mA. This provides the ability to drive various bus protocols such as Ethernet, USB, and Fibre Channel. The outputs of the transmitter can be configured as either tri-state or push-pull.

The ISL81485IBZ-T is widely used in various types of communication systems such as optical modems, wireless receivers, and digital television. In optical modems, the device is used to receiver and transmit data over an optical fiber. In wireless receivers, it is used to receive and transmit the high-frequency signals required for wireless transmission. In digital television systems, the device is used to receive and transmit digital television signals.

The ISL81485IBZ-T is an excellent choice for low-power, high-bandwidth communication systems. Its low-power, adjustable voltage range, noise immunity and versatile features make it ideal for use in many communication applications. Its reliable performance ensures that the ISL81485IBZ-T will remain a popular choice for many years to come.
