The SN74LV8T596-Q1
is an 8-bit shift register that feeds an 8-bit D-type storage register. Both the shift
register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If
both clocks are connected together, then the shift register always is one clock pulse
ahead of the storage register. All inputs include Schmitt-triggers allowing for slow
input transitions and providing more noise margin. Outputs QA through
QH are open-drain which require a pull-up resistor to output a High. The
serial output QH’ is push-pull.
