SN74LS645DW Overview
Logical driver uses a neat 20-SOIC (0.295, 7.50mm Width) package. Tube external packaging. Available in Surface Mount. Voltage buffer adopts Transceiver, Non-Inverting logic prototype. Buffer IC is fed with a voltage of 4.75V~5.25V. 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 74LS series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. In the LS family, the electric component belongs. 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 "74LS645" for other related electrical components. 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. 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. The typical output current of the logical driver is measured 24mA.
