3 Description
The SNx4HC594 devices contain an 8-bit serial-in,
parallel-out shift register that feeds an 8-bit D-type
storage register. Separate clocks and direct
overriding clear (RCLR, SRCLR) inputs are provided
on both the shift and storage registers. A serial (QH’)
output is provided for cascading purposes.
Both the shift register (SRCLK) and storage register
(RCLK) clocks are positive edge triggered. If both
clocks are connected together, the shift register
always is one count pulse ahead of the storage
register.
The parallel (QA QH) outputs have high-current
capability. QH’ is a standard output.
