SN74LS640-1NE4 Product Details

SN74LS640-1NE4 Overview


This package uses PDIP. A logical driver using the Rail/Tube external packaging is used in this application. It is necessary to use all 1 elements. Thebuffer features 20 terminations that serve different purposes. 5V is the required supply voltageThis buffer driver is part of the LS family of parts. With the electrical component, 20 pins are set. This logical driver is suitable for Through Hole different applications. In total, it has 20 pins. The transceiver features 2 ports for enhanced functionality. The recommended power supply is 5V. Users are advised to apply 5V supply voltage to the electronic part for the part to operate safely and reliably. This electronic part includes 8 efficient bits that can be used to increase efficiency. With WITH DIRECTION CONTROL, you can better serve your customers. There are 8 high-quality communication channels on this ethernet transceiver. A temperature as low as 0°C can be tolerated by this buffer. There should be no more than 70°C ambient temperature for the logical driver to operate. As a low-level output mode, it produces 15mA. During high-level output, the electronic part may conduct 24mA. At least 4.75V should be used in order to run this automotive buffer on a continuous basis. Approximately 5.25V are the maximum supply voltages. There is an bus transceiver called a BUS TRANSCEIVER logic chip. Buffer ICs are controlled by COMMON CONTROL control technology during startup.
