SN74LS165A

串行輸出移位寄存器; ? Complementary Outputs\n? Direct Overriding Load (Data) Inputs\n? Gated Clock Inputs\n? Parallel-to-Serial Data Conversion\nThe SN54165 and SN74165 devices are obsolete and are no longer supplied.;

The ?165 and ?LS165A are 8-bit serial shift registers that shift the data in the direction of QA toward QH when clocked. Parallel-in access to each stage is made available by eight individual, direct data inputs that are enabled by a low level at the shift/load (SH/LD\\) input. These registers also feature gated clock (CLK) inputs and complementary outputs from the eighth bit. All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design.\nClocking is accomplished through a two-input positive-NOR gate, permitting one input to be used as a clock-inhibit function. Holding either of the clock inputs high inhibits clocking, and holding either clock input low with SH/LD\\ high enables the other clock input. Clock inhibit (CLK INH) should be changed to the high level only while CLK is high. Parallel loading is inhibited as long as SH/LD\\ is high. Data at the parallel inputs are loaded directly into the register while SH/LD\\ is low, independently of the levels of CLK, CLK INH, or serial (SER) inputs.\n\n
