SN74ALS640B-1DWG4 Product Details

SN74ALS640B-1DWG4 Overview


Buffer uses a neat SOIC package. All of the 1 elements are put into use. 20 terminations with different functions. It reuqires a supply voltage of 5V. This electronic component belongs to the ALS family. 20 pins are set with the electrical part. It is suitable for Surface Mount applications. It has 20 pins. Enhanced with 2 ports. Specifically, It is a kind of Bus Driver/Transceivers. It is recommended to use a 5V power supply. It is generally sold in TUBE package. To run the part safely and stably in a circuit, 5V recommends users apply 5V on the lectronic component. 8 efficient bits are included within the network transceiver. Buffer features WITH DIRECTION CONTROL to better serve the need. This network transceiver has 8 channels for high quality communication. It is capable of operating under a temperature as low as 0°C. It should operate at an ambient temperature no higher than 70°C. Logical driver outputs 48mA in its low-level output mode. In high-level output mode, the electronic component may conduct -15mA of current. The voltage used to run this electrical part should be 4.75V at least. In regard to the maximum supply voltage, it is rated 5.25V. It is known as a BUS TRANSCEIVER logic IC. COMMON CONTROL control technology starts up the logical driver.
