DESCRIPTION
The 74LV595 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT595.
The74LV595 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 (D
S
) and a serial standard output
(Q
7’
) all 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.
