SN74AHC244PWE4 Product Details

SN74AHC244PWE4 Overview


This package uses TSSOP. A logical driver using the Rail/Tube external packaging is used in this application. It is necessary to use all 2 elements. Thebuffer features 20 terminations that serve different purposes. 3.3V is the required supply voltageThis buffer driver is part of the AHC/VHC/H/U/V 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/Transceivers are specifically types of them. During quiescent state, the electronic part uses 4μA. 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 8mA. During high-level output, the electronic part may conduct -8mA. At least 2V should be used in order to run this automotive buffer on a continuous basis. Approximately 5.5V are the maximum supply voltages. 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.
