SN74LS165N

8-BIT PARALLEL-TO-SERIAL SHIFT REGISTER The SN54 / 74LS165 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; new data enters via the Serial Data (DS) input. The 2-input OR clock can be used to combine two independent clock sources, or one input can act as an active LOW clock enable.

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. For clock operation, PL must be HIGH. The two clock inputs perform identically; one can be used as a clock inhibit by applying a HIGH signal. To avoid double clocking, however, the inhibit signal should only go HIGH while the clock is HIGH. Otherwise, the rising inhibit signal will cause the same response as a rising clock edge. The flip-flops are edge-triggered for serial operations. The serial input data can change at any time, provided only that the recommended setup and hold times are observed, with respect to the rising edge of the clock.

HOLD TIME (th) — is defined as the minimum time following the clock transition from LOW-to-HIGH that the logic level must be maintained at the input in order to ensure continued recognition. A negative hold time indicates that the correct logic level may be released prior to the clock transition from LOW-to-HIGH and still be recognized. RECOVERY TIME (trec) — is defined as the minimum time required between the end of the PL pulse and the clock transition from LOW-to-HIGH in order to recognize and transfer loaded Data to the Q outputs.
