54C165 Datasheet, National Semiconductor

Y Wide supply voltage range Y Guaranteed noise margin Y High noise immunity Y Low power TTL compatibility Y Parallel loading independent of clock Y Dual clock inputs Y Fu.

The MM54C165 MM74C165 functions as an 8-bit parallelload serial shift register Data is loaded into the register independent of the state of the clock(s) when PARALLEL LOAD (PL) is low Shifting is inhibited as long as PL is low Data is sequentially sh.
