SN74HC540DW Overview
Logical driver uses a neat 20-SOIC (0.295, 7.50mm Width) package. Tube external packaging. Available in Surface Mount. Voltage buffer adopts Buffer, Inverting logic prototype. Buffer IC is fed with a voltage of 2V~6V. Qualified to operate within -40°C~85°C TA. The high and low logic state output current of logical driver is 7.8mA 7.8mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74HC series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. This electronic component belongs to the HC/UH family. 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. You can search "74HC540" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceiver. The digital buffer starts up under ENABLE LOW control technology. In quiescent state, the electronic part uses 8μA. It is recommended to use a 2/6V power supply. To run the part safely and stably in a circuit, 5V recommends users apply 5V on the logical driver. To supply the device, a minimum voltage of 2V is a must. 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. It is sufficient to make 8 outputs.
