74HCT646NT Product Details

74HCT646NT Overview


24 terminations are present in this ethernet transceiver, each of which serves a different purpose. A supply voltage of 5V is required. In the HCT family, the electric component belongs. The electric component includes 24 pins. 2 ports have been added to this bus transceiver. In specific, buffer belongs to the Bus Driver/Transceiver family. The power supply should be 5V . There must be a minimum voltage of 4.5V in order to supply the digital buffer. There are 8 efficient bits in the package that make up the network transceiver. To better serve the needs, it features WITH DIRECTION CONTROL. An IC with REGISTERED BUS TRANSCEIVER logic is also known as a REGISTERED BUS TRANSCEIVER digital buffer. Using the POSITIVE EDGE trigger, the transceiver can be configured to monitor the logic analyzer inputs for a specific pattern. There is a high limit of ambient temperature for this buffer, which is 85°C. It is recommended to use a bottom temperature of -40°C with the electronic part. Logical drivers powered by INDEPENDENT CONTROL control technology start up automatically.
