description/ordering information
The ’LV594A devices are 8-bit shift registers
designed for 2-V to 5.5-V V
CC
operation.
These devices contain an 8-bit serial-in,
parallel-out shift register that feeds an 8-bit D-type
storage register. Separate clocks (RCLK, SRCLK) and direct overriding clear (RCLR
, SRCLR) inputs are
provided on the shift and storage registers. A serial output (Q
H′
) is provided for cascading purposes.
