... SN74LS165 8-Bit Parallel-to-Serial Shift Register The SN74LS165 is an 8-bit parallel load or serial-in register with complementary outputs available from the last stage. Parallel inputing occurs asynchronously when the Parallel Load (PL) input is LOW. With PL HIGH, serial shifting occurs on the rising edge of the clock; ...

... CC GND = PIN 8 = PIN NUMBERS FUNCTIONAL DESCRIPTION The SN74LS165 contains eight clocked master/slave RS flip-flops connected as a shift register, with auxiliary gating to provide overriding asynchronous parallel entry. Parallel data enters when the PL signal is LOW. The parallel data can change while PL is LOW, provided that the recommended setup and hold times are observed ...
