The functions of CLK and CLK INH are interchangeable. Since a low CLK and a low-to-high transition of CLK INH also accomplish clocking, CLK INH should be changed to the high level only while CLK is high. Parallel loading is inhibited when SH/LD is held high. While SH/LD is low, the parallel inputs to the register are enabled independently of the levels of the CLK, CLK INH, or serial (SER) inputs. FUNCTION TABLE INPUTS FUNCTION SH/LD CLK CLK INH FUNCTION L X X Parallel load H H X No change H X H No change H L ↑ Shift† H ↑ L Shift† † Shift = content of each internal register shifts toward serial output QH. Data at SER is shifted into the first register. logic diagram (positive logic) S 1D R C1 S 1D R C1 S 1D R C1 S 1D R C1 S 1D R C1 S 1D R C1 S 1D R C1 S 1D R C1 1 15 2 10 SH/LD CLK INH CLK SER 9 7 QH QH 11 12 13 14 3 4 5 6 AB C D EF G H Pin numbers shown are for the D, DB, J, N, NS, PW, and W packages. |
