SN54ALS643AJ Product Details

SN54ALS643AJ Overview


20 terminations with different functions. It reuqires a supply voltage of 5V. This electronic component belongs to the ALS family. 20 pins are set with the electrical part. Enhanced with 2 ports. To supply the digital buffer, a minimum voltage of 4.5V is a must. 8 efficient bits are included within the network transceiver. Buffer features WITH DIRECTION CONTROL to better serve the need. It is known as a BUS TRANSCEIVER logic IC. The high limit of ambient temperature for this logic buffer is 125°C. The bottom temp to go with the electronic component should be -55°C.
