DESCRIPTION
The M74HCT165 is an high speed CMOS 8 BIT PISO SHIFT REGISTER fabricated with silicon gate C2MOS technology.
This device contains eight clocked master slave RS flip-flops connected as a shift register, with auxiliary gating to provide over-riding asynchronous parallel entry. Parallel data enters when the shift/load input is low. The parallel data can change while shift/load is low, provided that the recommended set-up and hold times are observed. For clocked operation, shift/load must be high. The two clock input perform identically; one can be used as a clock inhibit by applying a high signal; to permit this operation clocking is accomplished through a 2 input nor gate.
