8-BIT PARALLEL-LOAD SHIFT

REGISTER



DESCRIPTION

The U74HCT165 is an 8-bit parallel-load shift register that,

Parallel-in access to each stage is provided by eight individual

direct data (A-H) inputs these are enabled by a low level at

shift/load (SH/ LD ) input. The U74HCT165 also features a

Q

)

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.

Since a low CLK and a low-to-high transition of CLK INH also

accomplish 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. 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.

The inputs are compatible with TTL,NMOS and CMOS output

voltage levels.
