3 Description
The SNx4HC165 devices are 8-bit parallel-load shift
registers that, when clocked, shift the data toward a
serial (QH) output. Parallel-in access to each stage is
provided by eight individual direct data (AH) inputs
that are enabled by a low level at the shift/load
(SH/LD) input. The SNx4HC165 devices also feature
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. Because a low CLK and a
low-to-high transition of CLK INH also accomplish
clocking, CLK INH must 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.
