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.
NC – No internal connection
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.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
