Abstract: MOTOROLA â I SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting and Nonin verting Bus Transceiver High-Performance Silicon-Gate CMOS The MC54/74HC643 is identical in pinout to the LS643. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC643 is a 3-state transceiver that is used for 2-way asynchronous communication , to A. The HC643 performs functions similar to those of the HC245 and the HC640. â'¢ Output Drive -
