Logical driver uses a neat 20-TSSOP (0.173, 4.40mm Width) package. Tape & Reel (TR) 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 -40°C~85°C TA. The high and low logic state output current of logical driver is 32mA 64mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74ABT series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Electronic parts from the ABT family are used in this part. 20 pins are set with the electric part. Enhanced with 2 ports. The bus transceiver employs 8 bits for each element. You can search "74ABT540" 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. It is recommended to use a 5V power supply. It is generally sold in TAPE AND REEL package. To supply the device, a minimum voltage of 4.5V is a must. Logical driver features WITH DUAL OUTPUT ENABLE to better serve the need.
