SN74S240NE4 Product Details

SN74S240NE4 Overview


This package uses PDIP. A logical driver using the Rail/Tube external packaging is used in this application. Thebuffer features 20 terminations that serve different purposes. 5V is the required supply voltageThis buffer driver is part of the S 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. During quiescent state, the electronic part uses 100mA. 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 6 efficient bits that can be used to increase efficiency. 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 64mA. During high-level output, the electronic part may conduct -15mA. 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. In addition to this, it can output 3 signals as well. This unit is more cost-effective for transmitting signals due to its 8 lines level input capability. There is an bus transceiver called a BUS DRIVER logic chip. 4 inputs are characterized by this digital buffer. Bus transceiver works on the basis of 2 circuits. Buffer ICs are controlled by ENABLE LOW control technology during startup.
