The SGM65231 is an 8-Bit, low voltage and high bandwidth bus switch. It supports rail-to-rail switching on data I/O ports and the power supply range is designed from 2.3V to 3.6V.
The SGM65231 has low on-resistance (RON) and low data I/O capacitance. These features make the device allow for minimal propagation delay and minimize signal distortion on the data bus.
It is recommended to connect a pull-up resistor between the OE pin and VCC pin to ensure high impedance during power-on or power-off. The ability of the driver to absorb current can determine the minimum value of the resistor.
The SGM65231 is designed with an IOFF circuitry. When the device is powered down, the IOFF circuitry can effectively prevent the destructive current backflow, and the SGM65231 has an isolation function in the state of power-off. This feature is widely used in partial-power-down applications.
The SGM65231 is suitable in a variety of applications such as high bandwidth equipment, broadband communications and data-intensive computing systems.
The SGM65231 is available in Green TQFN-4.5×3.5-20L and TSSOP-20 packages. It operates over an operating temperature range of -40℃ to +125℃.
