7.4 Device Functional Modes

Table 7-1 and Table 7-2 list the functional modes of the SN74LVC165A-Q1.

Table 7-1 Operating Mode Table
INPUTS(1) FUNCTION
SH/LD CLK CLK INH
L X X Parallel load(2)
H H X No change
H X H No change
H L ↑ Shift(3)
H ↑ L Shift(3)
(1) H = High Voltage Level, L = Low Voltage Level, X = Don't Care, ↑ = Low to High transition
(2) Parallel load : Values at inputs A through H are loaded to respective internal registers.
(3) Shift : Content of each internal register shifts towards serial output QH. Data at SER is shifted into the first register.
Table 7-2 Output Function Table
INTERNAL REGISTERS(1)(2) OUTPUTS(3)
A — G H Q Q
X L L H
X H H L
(1) Internal registers refer to the shift registers inside the device. These values are set by either loading data from the parallel inputs, or by clocking data in from the serial input.
(2) H = High voltage level, L = Low voltage level, X = Don't care
(3) H = Driving high, L = Driving low
