SN74LS645NE4 Product Details

SN74LS645NE4 Overview


Using a PDIP package makes it very easy to use. As you can see, this voltage buffer is packaged externally in the Rail/Tube package. 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 Through Hole 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. 5V power supplies are recommended. 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 15mA. It is possible for the electronic part to conduct 24mA 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.
