SN74ALS244CDWRE4 Product Details

SN74ALS244CDWRE4 Overview


SOIC packages are used to implement buffer. It is packaged in the Tape and Reel external packaging type for this voltage buffer. Transceiver uses all 2 elements. 20 terminations are present in this ethernet transceiver, each of which serves a different purpose. A supply voltage of 5V is required. In the ALS family, the electric component belongs. The electric component includes 20 pins. There are Surface Mount 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. In specific, buffer belongs to the Bus Driver/Transceivers family. The power supply should be 5V . Users should apply 5V supply voltage to the lectronic component in order to run it safely and reliably in a circuit. Under 0°C, it can operate. The ambient temperature should not exceed 70°C. Low-level mode outputs 24mA by default. High-level output mode allows -15mA of current to flow through the electronic component. In order for this electrical component to work properly, it should be operated at a voltage of at least 4.5V. It is rated 5.5V for maximum supply voltage. An IC with BUS DRIVER logic is also known as a BUS DRIVER digital buffer. In this case, 8 outputs will be sufficient. Logical drivers powered by ENABLE LOW control technology start up automatically.
