SN74LS640DWG4 Overview
Logical driver uses a neat SOIC package. All of the 1 elements are put into use. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Electronic parts from the LS family are used in this part. 20 pins are set with the electric part. Buffer IC is suitable for Surface Mount applications. Logical driver has 20 pins. Enhanced with 2 ports. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under COMMON CONTROL control technology. 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 logical driver. 8 bits are included within the electrical component. Logical driver features WITH DIRECTION CONTROL to better serve the need. 8 channels for high quality communication. Voltage buffer is capable of operating under temperature as low as 0°C. Digital buffer should operate with ambient temperature no higher than 70°C. Buffer driver outputs 24mA to its low level. In high level output mode, the electronic parts may conduct -15mA of current. Voltage used to run voltage buffer should be 4.75V at least. In regard to the maximum supply voltage, buffer driver is rated 5.25V. It is known as a BUS TRANSCEIVER logic IC.
