74HC646N,652 Overview
Logical driver uses a neat 24-DIP (0.600, 15.24mm) package. Tube external packaging. Available in Through Hole. Voltage buffer adopts Transceiver, Non-Inverting logic prototype. Buffer IC is fed with a voltage of 2V~6V. Qualified to operate within -40°C~125°C TA. The high and low logic state output current of logical driver is 7.8mA 7.8mA. Logical driver can deal with 3-State output (s). All of the 1 elements are put into use. Digital buffer is one of the 74HC series devices. 24 terminations with different functions. Buffer IC reuqires a supply voltage of 5V. Family HC/UH includes the buffer IC . 24 pins are set with the electric part. Enhanced with 2 ports. The bus transceiver employs 8 bits for each element. You can search "74HC646" 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. It is recommended to use a 2/6V power supply. To supply the device, a minimum voltage of 2V is a must. Logical driver features WITH DIRECTION CONTROL to better serve the need. Logical driver adapts POSITIVE EDGE trigger.
