Serial-in shift registers with output latches - SN74LS594
Datasheet
 

Description

These devices each contain an 8-bit D-type sorage 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 (QH') is provided for cascading purposes.

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