M74HC244B1R Overview

20-DIP (0.300, 7.62mm) packages are used to implement buffer. It is packaged in the Tube external packaging type for this voltage buffer. This digital buffer is available in the Through Hole mount. There are a variety of applications for Buffer, Non-Inverting logic integrated circuits. The logic IC is powered by 2V~6V. An ambient temperature of -55°C~125°C TA is suitable for this logical driver. There is a 7.8mA 7.8mA output current in the high and low logic states. 3-State outputs are supported. Transceiver uses all 2 elements. This is a network transceiver from the 74HC series. 20 terminations are present in this ethernet transceiver, each of which serves a different purpose. A supply voltage of 4.5V is required. In the HC/UH family, the electric component belongs. The electric component includes 20 pins. There are Through Hole applications for it. There are 20 pins on it. 2 ports have been added to this bus transceiver. Each element is represented by 4 bits. M74HC244 has other related electronic components that you can search for. In specific, buffer belongs to the Bus Driver/Transceivers family. 4μA is used by the electronic component in its quiescent stateThere must be a minimum voltage of 2V in order to supply the digital buffer. This device is capable of outputting 3 different signals simultaneously. Due to its 8 line input capability, it is more cost-effective when transmitting signals. Logical drivers powered by ENABLE LOW control technology start up automatically.
