8-BIT PARALLEL-LOAD SHIFT



DESCRIPTION

The U74HC165 is an 8-bit parallel-load shift register that,

SOP-16

when clocked, shifts the data toward a serial (Q_H) 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

shift/load (SH/ LD ) input. The U74HC165 also features a

clock-inhibit (CLK INH) function and a complementary serial ( Q_H)

output.

Clocking is accomplished by a low-to-high transition of the

TSSOP-16

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.
