... They are particularly attractive for implementing buffer registers, I/O ports, bidi- rectional bus drivers, and working registers. The registers in the DM74AS651 and DM74AS652 are edge-triggered D-type flip-flops. On the positive transition of the clock (CAB or CBA), the input data is stored. ...

... LOW-to-HIGH transition on the clock inputs. Note 2: If the select control is LOW, the clocks can occur simultaneously. If the select control is HIGH, the clocks must be staggered in order to load both registers. www.fairchildsemi.com DATA I/O (Note 1) OPERATION OR FUNCTION A1 B1 DM74AS651 THRU THRU A8 B8 Isolation Input Input ...
