The SN74HCS594 device contains an 8-bit, serial-in, parallel-out shift
register that feeds an 8-bit D-type storage register. All inputs include Schmitt
triggers, eliminating any erroneous data outputs due to slow-edged or noisy input
signals. The storage register has parallel outputs. Separate clocks and direct
overriding clear (SRCLR, RCLR) inputs are
provided for both the shift and storage register. A serial output (QH)
is provided for cascading.
Both the shift register (SRCLK) and storage register (RCLK) clocks are positive edge
triggered. If both clocks are connected together, the shift register is one count
pulse ahead of the storage register.
