SN74LS640-1DWG4 Product Details

SN74LS640-1DWG4 Overview


SOIC packages are used to implement buffer. Transceiver uses all 1 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 LS 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. The power supply should be 5V . TUBE packages are generally used. Users should apply 5V supply voltage to the lectronic component in order to run it safely and reliably in a circuit. There are 8 efficient bits in the package that make up the network transceiver. To better serve the needs, it features WITH DIRECTION CONTROL. Logic ICs with 8 channels provide high-quality communication. 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 4.75V. It is rated 5.25V for maximum supply voltage. An IC with BUS TRANSCEIVER logic is also known as a BUS TRANSCEIVER digital buffer. Logical drivers powered by COMMON CONTROL control technology start up automatically.
