3 Description
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 QH'.
