... They are particularly attractive for implementing buffer registers, I/O ports, bidi- rectional bus drivers, and working registers. The registers in the DM74ALS646 are edge-triggered D- type flip-flops. On the positive transition of the clock (CAB or CBA), the input bus data is stored into the appropriate register ...
