SN74LS540NE4 Product Details

SN74LS540NE4 Overview


Logical driver uses a neat PDIP package. Rail/Tube external packaging. All of the 1 elements are put into use. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Transceiver shares the LS family's comprehensive benefits and features. 20 pins are set with the electric part. Buffer IC is suitable for Through Hole applications. Logical driver has 20 pins. Enhanced with 2 ports. It is recommended to use a 5V power supply. 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 DUAL OUTPUT ENABLE 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 DRIVER logic IC. ENABLE LOW control technology is used to start up the automotive buffer.
