ZHCSO37A October 2020 – May 2021 SN74HCS594
PRODUCTION DATA
The SN74HCS594-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, 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.
