The CD4034BM CD4034BC is an 8-bit CMOS static shift register with two parallel bidirectional data ports (A and B) which when combined with serial shifting operations can be used to (1) bidirectionally transfer parallel data between two buses (2) convert serial data to parallel form and direct them to either of two buses (3) store (recirculate) parallel data or (4) accept parallel data from either of two buses and convert them to serial form These operations are controlled by five control inputs A ENABLE (AE) ‘‘A’’ data port is enabled only when AE is at logical ‘‘1’’ This allows the use of a common bus for multiple packages A-BUS-TO-B-BUS B-BUS-TO-A-BUS (A B) This input controls the direction of data flow When at logical ‘’1’’ data flows from port A to B (A is input B is output) When at logical ‘‘0’’ the data flow direction is reversed ASYNCHRONOUS SYNCHRONOUS (A S) When A S is at logical ‘‘0’’ data transfer occurs at positive transition of the CLOCK When A S is at logical ‘‘1’’ data transfer is independent of the CLOCK for parallel operation In serial mode A S input is internally disabled such that operation is always synchronous (Asynchronous serial operation is not possible ) PARALLEL SERIAL (P S) A logical ‘‘1’’ P S input allows data transfer into the registers via A or B port (synchronous if A S e logical ‘‘0’’ asynchronous if A S e logical ‘‘1’’) A logical ‘‘0’’ P S allows serial data to transfer into the register synchronously with the positive transition of the CLOCK independent of the A S input CLOCK Single phase enabled only in synchronous mode (Either P S e logical ‘‘1’’ and A S e logical ‘‘0’’ or P S e logical ‘‘0’’ All register stages are D-type master-slave flip-flops with separate master and slave clock inputs generated internally to a
