SN74LS243DR Overview
Logical driver uses a neat 14-SOIC (0.154, 3.90mm Width) package. Tape & Reel (TR) 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 Push-Pull output (s). All of the 1 elements are put into use. Digital buffer is one of the 74LS series devices. 14 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Electronic parts from the LS family are used in this part. 14 pins are set with the electric part. Buffer IC is suitable for Surface Mount applications. Logical driver has 14 pins. Enhanced with 2 ports. You can search "74LS243" for other related electrical components. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under INDEPENDENT CONTROL control technology. In quiescent state, the electronic part uses 32mA. 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. 4 bits are included within the electrical component. Logical driver features WITH INDEPENDENT OUTPUT ENABLE FOR EACH DIRECTION to better serve the need. 4 channels for high quality communication.
