Description

This device each contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The

storage register has parallel 3-state outputs. Separate clocks are provided for both the shift register and the storage

register. The shift register has a direct-overriding clear, serial input, and serial output pins for cascading.

Both the shift register and storage register clocks are positive-edge triggered. If the user wishes to connect both clocks

together, the shift register state will always be one clock pulse ahead of the storage register.
