SCLS116H – DECEMBER 1982 – REVISED DECEMBER 2015 SNx4HC165 8-Bit Parallel-Load Shift Registers
1 Features 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 (A-H) 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. 1 Wide Operating Voltage Range of 2 V to 6 V
Outputs Can Drive Up to 10 LSTTL Loads
Low Power Consumption, 80-ВµA Maximum ICC
Typical tpd = 13 ns
В±4-mA Output Drive at 5 V
Low Input Current of 1 ВµA Maximum
Complementary Outputs
Direct Overriding Load (Data) Inputs
Gated Clock Inputs …
