Logical driver uses a neat 20-VFQFN Exposed Pad package. Tape & Reel (TR) external packaging. Available in Surface Mount. Voltage buffer adopts Buffer, Non-Inverting logic prototype. Buffer IC is fed with a voltage of 4.5V~5.5V. Qualified to operate within -40°C~125°C TA. The high and low logic state output current of logical driver is 8mA 8mA. Logical driver can deal with 3-State output (s). All of the 2 elements are put into use. Digital buffer is one of the Automotive, AEC-Q100, 74AHCT series devices. 20 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. In the AHCT/VHCT/VT 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. The bus transceiver employs 4 bits for each element. You can search "74AHCT244" for other related electrical components. In quiescent state, the electronic part uses 4μA. To run the part safely and stably in a circuit, 5V recommends users apply 5V on the logical driver. It is sufficient to make 8 outputs.
