DESCRIPTION
'HC595 devices contain 8-bit serial-in, parallel-out shift register that feeds 8-bit D-type storage register. storage register parallel 3-state outputs. Separate clocks provided both shift storage register. shift register direct overriding clear (SRCLR) input, serial (SER) input, serial outputs cascading. When output-enable (OE) input high, outputs high-impedance state. Both shift register clock (SRCLK) storage register clock (RCLK) positive-edge triggered. both clocks connected together, shift register always clock pulse ahead storage register.
