U74HC165
8-BIT PARALLEL-LOAD SHIFT
REGISTER
DESCRIPTION
The U74HC165 is an 8-bit parallel-load shift register that,
when clocked, shifts the data toward a serial (QH) output.
Parallel-in access to each stage is provided by eight individual
direct data (A-H) inputs that are enabled by a low level at
shift/load (SH/ LD ) input. The U74HC165 also features a
clock-inhibit (CLK INH) function and a complementary serial ( QH )
output.
Clocking is accomplished by a low-to-high transition of the
clock (CLK) input while SH/ LD is held high and CLK INH is held
low. 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.
FEATURES
* Complementary Outputs
* Direct Overriding Load (Data) Inputs
* Gated Clock Inputs
* Parallel-to-Serial Data Conversion
