MC74AC244DWR2 Product Details

MC74AC244DWR2 Overview


This package uses SOIC. A logical driver using the Cut Tape external packaging is used in this application. It is necessary to use all 2 elements. Thebuffer features 20 terminations that serve different purposes. 5V is the required supply voltageThis buffer driver is part of the AC family of parts. With the electrical component, 20 pins are set. This logical driver is suitable for Surface Mount different applications. In total, it has 20 pins. The transceiver features 2 ports for enhanced functionality. Each element uses 4 bits. Bus Driver/Transceiverss are specifically types of them. During quiescent state, the electronic part uses 8μA. TAPE AND REEL packages are usually sold. Users are advised to apply 5V supply voltage to the electronic part for the part to operate safely and reliably. A temperature as low as -40°C can be tolerated by this buffer. There should be no more than 85°C ambient temperature for the logical driver to operate. As a low-level output mode, it produces 24mA. During high-level output, the electronic part may conduct -24mA. At least 2V should be used in order to run this automotive buffer on a continuous basis. Approximately 6V are the maximum supply voltages. In addition to this, it can output 3 signals as well. There is an bus transceiver called a BUS DRIVER logic chip. This is sufficient to produce 8 outputs from it. Buffer ICs are controlled by ENABLE LOW control technology during startup.
