description
The
′ALS165 are parallel-load 8-bit serial shift
registers that, when clocked, shift the data toward
serial (QH and QH) outputs. Parallel-in access to
each stage is provided by eight individual direct
data (A H) inputs that are enabled by a low level
at the shift/load (SH/LD) input. The
′ALS165 have
a clock-inhibit function and complemented serial
outputs.
Clocking is accomplished by a low-to-high
transition of the clock (CLK) input while SH/LD is
held high and the clock inhibit (CLK INH) input 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
accomplishes 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. The parallel inputs to the register are
enabled while SH/LD is low independently of the
levels of the CLK, CLK INH, or serial (SER) inputs.
The SN54ALS165 is characterized for operation over the full military temperature range of 55
°C to 125°C. The
SN74ALS165 is characterized for operation from 0
°C to 70°C.
