Signal buffers, repeaters, splitters, as a kind of interface product, are used to restructure signal of different ports to different standard which makes the signal more consistent and easier be used. Take MAX4952ACTI+ as an example, it is an high-performance, low-power octal bus switch and is a device of activating, electrically isolating, and accessing any of eight buses.

Application Field

MIN4952ACTI+ is broadly used in data communication, sensor networks, audio/visual equipment, and industrial control systems. Its applications contain SPI/I?C multiplexers, computer/peripheral switch, processor/memory switch and etc.

Work Principle

MAX4952ACTI+ works based on standard TTL or 5V bus signal and is able to turn off power for unused channels. It provides two logic-level enable pins which allow the device to select which buses should be switched on or off. It contains a single connect option which can enable the 4-channel multiplexer in a mode to pass signals from one side to another. Also, it states that device is able to operate in ultra-low-power mode which allows the device to remain in its current status when the enable pins are in logic low.

In terms of accuracy and control, the device switches 2.7V to 5.5V for eight digital buses and provides an active-high enable pin that enables the device or any of 8x2 peripherals. Also, it delivers a fast switching of up to 350ns, superior data accuracy with a low on-capacitance of 0.2pF and a low off-capacitance of 0.1pF. The device is specified for temperatures between -40°C to +85°C. What’s more, in order to protect connected devices, the MAX4952ACTI+ have a bus-hold feature which prevents the bus outputs from floating when the device turns off, and enabling the I/O buffer interface.

To sum up, MAX4952ACTI+ is a useful and necessary device in many occasions like industrial control and data communication. With the advantages above, it can be used in power saving mode with low power and accuracy, protecting the connected device.
