TEXAS INSTRUMENTS CMOS CD4094BE 8-Stage Bus Register, 8-Bit, DIP-16

The TEXAS INSTRUMENTS CD4094BE is a versatile 8-stage CMOS Shift-and-Store Bus Register designed for efficient serial data management. Each stage features an associated storage latch, enabling data to be strobed from the serial input to parallel buffered 3-state outputs. This design allows the parallel outputs to be directly connected to common bus lines, making it a cornerstone component for bus-oriented digital systems.

Data is shifted synchronously on positive clock transitions, ensuring precise timing control. The information within each shift register stage is transferred to the dedicated storage register whenever the strobe input is set to a high logic level. The stored data then appears at the outputs when the output-enable signal is high, providing complete control over data flow and bus contention.

For system integration and expansion, the register offers two serial outputs to accommodate different clock conditions. Data is available at the QS terminal on positive clock edges, facilitating high-speed operation in cascaded systems with fast clock rise times. Concurrently, the same serial information is presented at the Q'S terminal on the subsequent negative clock edge, providing a reliable method for cascading multiple CD4094BE devices in environments with slower clock rise times, thereby ensuring robust signal integrity across diverse operational speeds.

Key Features and Applications

• 3-State Parallel Outputs: Enables direct, contention-free connection to shared bus lines, a critical feature for multi-device communication.
• Dual Serial Outputs: Separate outputs synchronous to both positive and negative clock edges provide maximum flexibility for cascading registers in complex digital chains.
• Medium-Speed Operation: Capable of operating at frequencies up to 5MHz with a 10V supply, suitable for a wide range of digital signal processing tasks.
