ISL84053IBZ

The ISL84053IBZ is an interface device that acts as a multiplexer/demultiplexer, providing the ability to quickly and accurately assign individual pins on two control systems. This allows two independent micro-controller systems to achieve timing and synchronizing between them, as well as provide invaluable interfacing aid when controlling external devices. The ISL84053IBZ is applicable in a multitude of scenarios, offering increased speed and accuracy compared to comparable alternatives, as well as being optimized for low power consumption, making it a perfect fit for any application.

The ISL84053IBZ multiplexer/demultiplexer integrates an array of signal switches and logic designed for applications where two distinct signal systems need synchronizing or interfacing with each other. This device is capable of providing signal conversion for multiple signal paths such as SPI, I2C, serial, and digital interfaces. To support higher data rates, it has two individual bit-shift registers, enabling two chips to achieve fast-timing synchronization while minimizing power requirements and debris. The CPLD also includes two Latch registers per channel, providing the ability to store prefixed values and act as additional channels. Channel selection is on-chip, and is achieved either through the register proper or through external pins.

• Supports cascade shift registers.
• 24-bit shift register for faster signal conversion.
• On-chip register selection.
• External latch selection available.
• 3.3V operating voltage.
• 2MHz max shifting speed.
• Low power consumption.

The ISL84053IBZ is a suitable choice for both simple data transfer operations and more complex interfacing applications. Single chip interface solutions, such as micro-controllers, require this device to provide a means of synchronizing the two processors with fast switching and minimal power requirements. The ISL84053IBZ is also used in data acquisition and control systems, where it serves as a cost-effective and low-power alternative to comparably priced solutions. Additionally, the ISL84053IBZ is useful in automotive control systems, providing simplified synchronizing and interfacing between sub-assemblies and boards.

The ISL84053IBZ chip is a CPLD device which implements a multiplexer/demultiplexer design. The operation of the device is explained by its two primary components, the register and bit shifter. The register handles the majority of the device operations, including data conversion and selection of the channels, while the bit shifter manages incoming and outgoing data. The register is responsible for selecting the desired channels from a list of available pins, while the bit shifter routes the incoming data stream on the selected channels. This device is further optimized for lower power consumption, and is capable of operation at speeds up to 2MHz.
