description
The ’LV165 parallel-load, 8-bit shift registers are
designed for 2.7-V to 5.5-V VCC operation.
When the device is clocked, data is shifted toward
the serial output QH. Parallel-in access to each
stage is provided by eight individual direct data
inputs that are enabled by a low level at the SH/ LD
input. The ’LV165 feature a clock inhibit function
and a complemented serial output QH.
Clocking is accomplished by a low-to-high
transition of the clock (CLK) input while SH/ LD is
held high and clock inhibit (CLK INH) is held low. The functions of the CLK and CLK INH inputs are
interchangeable. Since a low CLK input and a low-to-high transition of CLK INH accomplishes 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. The parallel inputs to the register are enabled while SH/ LD is held low independently of the levels of CLK,
CLK INH, or SER.
The SN54LV165 is characterized for operation over the full military temperature range of –55
°C to 125°C. The
SN74LV165 is characterized for operation from –40
°C to 85°C.
