SN74LS240N Overview
Logical driver uses a neat 20-DIP (0.300, 7.62mm) package. Tube external packaging. Available in Through Hole. Voltage buffer adopts Buffer, 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 2 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. Enhanced with 2 ports. The bus transceiver employs 4 bits for each element. Specifically, digital transciever is a kind of Bus Driver/Transceivers. The digital buffer starts up under ENABLE LOW control technology. It is recommended to use a 5V power supply.
