SN74HC595B - 8-Bit Shift Registers With 3-State Output

The SN74HC595B devices contain an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift register and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the all outputs are in the high-impedance state except Q_H’.
