does anyone here knows how an 8 stage shift and store bus register, three state works... The device name particularly is HC4094F, I have very little background on bus registers and I just hope you could help me particularly that question of mine. Thanks...
Pin's 8 & 16 are the power supply.
Pin 15 (OE) Tristates the parallel outputs when low, enables them when high.
Pin 1 (Strobe) Needs to be high for the part to accept a new bit to shift in - when low data is ignored.
And then it's quite simple - On a positive edge on the clock pin (3), The bit on the data pin (2) is transferred to Q1. The bit that was on Q1 is tranferred to Q2 and so on.
So, if you clock 8 times you have a complete byte on the parallel outputs.
