The 74ACT520 are expandable 8-bit comparators. They compare two words of up to eight bits each and provide a LOW output when the two words match bit for bit. The expansion input IA = B also serves as an active LOW enable input.
IC REGISTER QUAD 2PORT 16SOP
The 74ACT399SJ is the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops. A common Select input determines which of the two 4-bit words is accepted. The selected data enters the flip-flop on the rising edge of the cl...
