DESCRIPTION HCF4034B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in SOP packages. HCF4034B is a static eight-stage parallel-or serial-input parallel-output register. It can be used to : 1) bidirectionally transfer parallel information between two buses ; 2) convert serial data to parallel form and direct the parallel data to either PIN CONNECTION

of the two buses ; 3) store (recirculate) parallel data, or 4) accept parallel data from either of the two buses and convert the data to serial form. Inputs that control the operations include a single-phase CLOCK (CL), A DATA ENABLE (AE), ASYNCHRONOUS/SYNCHRONOUS (A/ S), A-BUS-TO-B-BUS/B-BUS-TO-A-BUS (A/B), and PARALLEL/ SERIAL (P/S). Data inputs include 16 bidirectional parallel data lines of which the eight A data lines are inputs (3-state outputs) and the B data lines are outputs (inputs) depending on the signal level on the A/B input. In addition, an input for SERIAL DATA is also provided. All register stages are D-type master-slave flip-flops with separate master and slave clock inputs generated internally to allow

synchronous or asynchronous data transfer from master to slave. Isolation from external noise and the effects of loading is provided by output buffering. PARALLEL OPERATION - A high P/S input signal allows data transfer into the register via the parallel data lines synchronously with the positive transition of the clock, provided the A/S input is low. If the A/S input is high, the transfer is independent of the clock. The direction of data flow is controlled by the A/B input. When this signal is high the A data lines are inputs (and B data lines are outputs) ; a low A/B signal reverses the direction of data flow. The AE-input is an additional feature which allows many registers to feed data to a common bus. The A DATA lines are IINPUT EQUIVALENT CIRCUIT enabled only when this signal is high. Data storage through recirculation of data in each register stage is accomplished by making the A/B signal high and the AE signal low. SERIAL OPERATION - A low P/S signal allows serial data to transfer into the register synchronously with the positive transition of the clock. The A/S input is internally disabled when the register is in the serial mode (asynchronous serial operation is not allowed). The serial data appears as output data on either the B lines (when A/B is high) or the A lines (when A/B is low and the AE signal is high). Register expansion can be accomplished by simply cascading HCC/ HCF4034B packages. PIN DESCRIPTION

SHIFT RIGHT/SHIFT LEFT WITH PARALLEL INPUTS

A "High" ("Low") on the Shift Left/Shift Right input allows serial data on the Shift Left Input (Shift Right Input) to enter the register on the positive transition of the clock signal. A "high" on the "A" Enable Input disables the "A" parallel data lines on Reg. 1 and 2 and enables the "A" data lines on registers 3 and 4 and allows parallel data into

registers 1 and 2. Other logics schemes may be used in place of registers 3 and 4 for parallel loading. When parallel inputs are not used Reg. 3 and 4 and associated logic are not required. * Shift Left input must be disabled during parallel entry.
