SN74LS642NE4 Product Details

SN74LS642NE4 Overview


It utilizes a neat PDIP package. It uses all 1 elements. 20 terminations are provided by this buffer. Supply voltage must be 5V. There is a LS family part that is attached to this electronic component. With the electrical component, there are 20 pins. In total, it can be used for Through Hole different purposes. The cable has 20 pins. Transceiver with 2 ports. Power supplies with 5V should be used. A TUBE package is usually sold with it. For safe and stable operation, users should apply 5V supply voltage to the electrical component. This electronic component consists of 8 efficient bits that are included within it. In order to better meet the needs, network transceiver includes WITH DIRECTION CONTROL. Ethernet transceivers like this one provide high-quality communication over 8 channels. Temperatures as low as 0°C are possible with it. It should not operate at a temperature higher than 70°C. The low-level output mode of this voltage buffer outputs 24mA. During high-level output mode, the electrical part can conduct -15mA of current. This automotive buffer should operate at least at 4.75V, which is what is recommended by the manufacturer. It is rated 5.25V for maximum supply voltage. The IC is also called a BUS TRANSCEIVER transceiver. Buffer ICs are controlled by COMMON CONTROL control technology during startup.
