DM74LS165 8-Bit Parallel In/Serial Output Shift Registers August 1986 Revised March 2000 DM74LS165 8-Bit Parallel In/Serial Output Shift Registers General
This device is an 8-bit serial shift register which shifts data in the direction of QA toward QH when clocked. Parallel-in access is made available by eight individual direct data inputs, which are enabled by a low level at the shift/load input. These registers also feature gated clock inputs and complementary outputs from the eighth bit. Clocking is accomplished through a 2-input 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 the load input HIGH enables the other clock input. The clock-inhibit input should be changed to the high level only while the clock input is HIGH. Parallel loading is inhibited as long as the load input is HIGH. Data at the parallel inputs are loaded directly into the register [ … ]
