CD74HC640EE4 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. This logical driver is suitable for Through Hole different applications. In total, it has 20 pins. Each element uses 8 bits. During quiescent state, the electronic part uses 8 µA. This electronic part includes 8 efficient bits that can be used to increase efficiency. There are 8 high-quality communication channels on this ethernet transceiver. A temperature as low as -55 °C can be tolerated by this buffer. There should be no more than 125 °C ambient temperature for the logical driver to operate. As a low-level output mode, it produces 7.8 mA. During high-level output, the electronic part may conduct -7.8 mA. At least 2 V should be used in order to run this automotive buffer on a continuous basis. Approximately 6 V are the maximum supply voltages. Bus transceiver works on the basis of 8 circuits.
