Shift register input 8-bit 74HC165 SOP-16

Beschrijving

Description:
The SNx4HC165 devices are 8-bit parallel-load shift registers that, when clocked, shift 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 the shift/load (SH/LD) input. The SNx4HC165 devices also feature a clock-inhibit (CLK INH) function and a complementary serial (Q H ) 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 • Gated Clock Inputs INH are interchangeable. Because a low CLK and a low-to-high transition of CLK INH also accomplish clocking, CLK INH must be changed to the high level. All Parameters Are Tested Unless Otherwise only while CLK is high. Parallel loading is inhibited Noted. On All Other Products, Production when SH/LD is held high. While SH/LD is low, the Processing Does Not Necessarily Include Testing parallel inputs to the register are enabled independently of the levels of the CLK, CLK INH, or of All Parameters. serial (SER) inputs.
