DESCRIPTION
The 74HC/HCT595 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT595 is an 8-stage serial shift register with a
storage register and 3-state outputs. The shift register and
storage register have separate clocks.
Data is shifted on the positive-going transitions of the
SH_CP input. The data in each register is transferred to
the storage register on a positive-going transition of the
ST_CP input. If both clocks are connected together, the
shift register will always be one clock pulse ahead of the
storage register.
The shift register has a serial input (DS) and a serial
standard output (Q7’) for cascading. It is also provided
with asynchronous reset (active LOW) for all 8 shift
register stages. The storage register has 8 parallel 3-state
bus driver outputs. Data in the storage register appears at
the output whenever the output enable input (OE) is LOW.
