SN74LS640DWG4 Product Details

SN74LS640DWG4 Overview


Using a SOIC package makes it very easy to use. Transceiver utilizes all 1 elements. There are 20 terminations on this ethernet transceiver, all of which perform different functions. 5V is required for its operation. This logical driver is a member of the LS family. The electric component has 20 pins. A total of Surface Mount applications can be accommodated by logical driver. A total of 20 pins are present on digital buffer. With 2 ports, this logic device is enhanced. The type of Bus Driver/Transceivers buffer is is specifically Bus Driver/Transceivers. 5V power supplies are recommended. TUBE packages are generally sold. Users should apply 5V to the electronic part to ensure safe and stable operation in a circuit. As part of the electronic component, there are 8 efficient bits that are included. As a result, automotive buffer features WITH DIRECTION CONTROL to better meet the customer's needs. For high-quality communication, this network transceiver has 8 channels. Under a temperature of 0°C, buffers can operate. Ambient temperatures should not exceed 70°C. When it is set to low-level output, voltage buffer outputs 24mA. It is possible for the electronic part to conduct -15mA of current when operating on high-level output mode. There should be a voltage at least of 4.75V used to run this buffer. As far as maximum supply voltage is concerned, it is rated at 5.25V. Bus transceivers such as this are called BUS TRANSCEIVER ICs. Using COMMON CONTROL control technology, the voltage buffer begins to operate.
