... M74LCX646 (enable G high), "A" data may be stored in one register and/or "B" data may be stored in the other register. When an output function is disabled, the input function is still enabled and may be used to store and transmit data. Only one of the two buses may be driven at a time. It has same speed performance at 3 ...
