74HC165D

The 74HC165D is a high speed CMOS 8-BIT PARALLEL/SERIAL-IN, SERIAL-OUT SHIFT REGISTER
fabricated with silicon gate C
2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power
dissipation.
It consists of parallel-in or serial-in, serial-out 8-bit shift register with a gated clock inputs. When the SHIFT/
LOAD input is held high, the serial data input is enabled and the eight frip-frops perform serial shifting with
each clock pulse.
When the SHIFT/LOAD input is held low, the parallel data is loaded synchronously into the register at positive
going transition of the clock pulse.
The CK-INH input should be shifted high only when the CK input is held high.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
