Octal 3-State Inverting Bus Transceiver
High–Performance Silicon–Gate CMOS
The MC54/74HC640A is identical in pinout to the LS640. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC640A is a 3–state transceiver that is used for 2–way asynchr...
