The CD4034B is a static eight-stage parallel-or serial-input parallel-output register.

Features of CD4034 8-Stage Bidirectional Bus Register:

• Bidirectional parallel data input.
• Parallel or serial inputs/parallel outputs.
• Asynchronous or synchronous parallel data loading.
• Parallel data-input enable on "A" data lines (3-state output).
• Data Recirculation for register expansion.
• Multi-package register expansion.
• Fully static operation dc-to-10 MHz (typ.) at VDD = 10 V.

Applications of CD4034 8-Stage Bidirectional Bus Register:

• Parallel Input/Parallel Output, Serial Input/Parallel Output, Serial Input/Serial Output Register.
• Shift right/shift left register.
• Shift right/shift left with parallel loading.
• Address register.
• Buffer register.
• Bus system register with enable parallel lines at bus side.
• Double bus register system.
• Up-Down Johnson or ring counter.
• Pseudo-random code generators.
• Sample and hold register (storage, counting, display).
• Frequency and phase comparator.
