SN74HC244DWE4 Product Details

SN74HC244DWE4 Overview


It utilizes a neat SOIC package. A logical driver like this one is packaged using an external packaging called Rail/Tube. It uses all 2 elements. 20 terminations are provided by this buffer. Supply voltage must be 5V. There is a HC/UH family part that is attached to this electronic component. With the electrical component, there are 20 pins. In total, it can be used for Surface Mount different purposes. The cable has 20 pins. Transceiver with 2 ports. Each element utilizes 4 bits. Electronic part 8μA is used in a quiescent stateFor safe and stable operation, users should apply 5V supply voltage to the electrical component. Temperatures as low as -40°C are possible with it. It should not operate at a temperature higher than 85°C. The low-level output mode of this voltage buffer outputs 7.8mA. During high-level output mode, the electrical part can conduct -7.8mA of current. This automotive buffer should operate at least at 2V, which is what is recommended by the manufacturer. It is rated 6V for maximum supply voltage. The IC is also called a BUS DRIVER transceiver. As you can see, it is enough for 8 outputs to be generated. Buffer ICs are controlled by ENABLE LOW control technology during startup.
