SN74ALS540DWR Overview
Logical driver uses a neat 20-SOIC (0.295, 7.50mm Width) package. Cut Tape (CT) external packaging. Available in Surface Mount. Voltage buffer adopts Buffer, Inverting logic prototype. Buffer IC is fed with a voltage of 4.5V~5.5V. Qualified to operate within 0°C~70°C TA. The high and low logic state output current of logical driver is 15mA 24mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74ALS series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. This buffer driver is part of the ALS family of parts. 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 "74ALS540" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under ENABLE LOW control technology. In quiescent state, the electronic part uses 13mA. It is recommended to use a 5V power supply. It is generally sold in TR 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 DUAL OUTPUT ENABLE to better serve the need. 8 channels for high quality communication. It is sufficient to make 8 outputs.
