description

These devices each contain an 8-bit D-type storage
register. The storage register has buffered (‘LS594) or
open-collector (‘LS599) outputs. Separate clocks and
direct-overriding clears are provided on both the shift
and storage registers. A shift output (Q*) is provided
for cascading purposes.

Both the shift register and the storage register clocks
are positive-edge triggered. If the user wishes to con-
nect both clocks together, the shift register will always
be one clock pulse ahead of the storage register.
