Part Number | U74HC165 |
Manufacturer | UTC |
Description | The U74HC165 is an 8-bit parallel-load shift register that, when clocked, shifts the data toward a serial (QH) output. Parallel-in access to each stage is provided by eight individual direct data (A-H... |
Features |
a
clock-inhibit (CLK INH) function and a complementary serial ( QH ) 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) ... |
