BU9728AKV-E2 Product Details

BU9728AKV-E2 Overview


As with Tape & Reel (TR), the package is designed similarly.Display drivers is included in the package version 48-LQFP.This electrical device has a display type of LCD, which is the display type of the device.On the board, this component is mounted using Surface Mount.Display drivers is operating at -40°C~85°C degrees FahrenheDisplay drivers.I believe that it will work with a 2.5V~5.5VV power source.An impedance-matching device is used to terminate transmission lines using a 48 termination.BU9728A devices are among the devices in this family.A 48 pin is the component that makes up the entire device.The 48-pin design is what makes it so unique.A Surface Mount-axis is used in the manufacturing of this electronic component for mounting on the board.There is a need to supply 40μA with the necessary supply current for it to function at full capacity.128 segments refer to any member of the Seller Group's equipment solutions business that falls under the category of "Electronics.".Other Interface ICs can also include it as part of the equation.In order to achieve high efficiency, it is necessary to maintain the supply voltage at 5.5V.In addition, it can be operated from anywhere in the world by two 3/5V power supplies.As soon as the maximum current is supplied for its operation, the voltage reaches 250μA.A 4-BP backplane is an electronic circuits board that is used as a backplane.The frequency of the device is 36kHz.
