4-BIT D-TYPE REGISTERS WITH 3-STATE OUTPUTS

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. Clocking 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. By Texas Instruments
