If trailing-zero suppression is required, the direction of ripple-blanking datasueet must be reversed with the RBI terminal of the LSD grounded and its RBO terminal wired to the 74ls terminal of the next least-significant 74ld47, and so on.
Feb 9, 6. Basic way of using the B to drive a seven-segment common-cathode LED display.
Some of these devices have integral ripple-blanking facilities, others have built-in data latches, and a few even have built-in decade counter stages, etc. The 74LS47 has active-low outputs designed for driving a common-anode LED display via external current-limiting resistors Rxas shown in Figure 2. The B has four input control terminals, and three auxiliary dataaheet terminals.
The relative positive-logic output levels, as well as conditions required at the auxiliary inputs, are shown in the truth tables. Full text of ” IC Datasheet:
