SN74AC244NE4 Product Details

SN74AC244NE4 Overview


Buffer uses a neat PDIP package. This logic IC uses the Rail/Tube external packaging. All of the 2 elements are put into use. 20 terminations with different functions. It reuqires a supply voltage of 3.3V. This electronic component belongs to the AC family. 20 pins are set with the electrical part. It is suitable for Through Hole applications. It has 20 pins. Enhanced with 2 ports. The network transceiver employs 4 bits for each element. Specifically, It is a kind of Bus Driver/Transceivers. In quiescent state, the electronic component uses 4μA. It is recommended to use a 3.3/5V power supply. It is capable of operating under a temperature as low as -40°C. It should operate at an ambient temperature no higher than 85°C. Logical driver outputs 24mA in its low-level output mode. In high-level output mode, the electronic component may conduct -24mA of current. The voltage used to run this electrical part should be 2V at least. In regard to the maximum supply voltage, it is rated 6V. It is known as a BUS DRIVER logic IC. It is sufficient to make 8 outputs. ENABLE LOW control technology starts up the logical driver.
