The 74HCT4094D is a high-speed Si-gate CMOS device from NXP Semiconductors, designed to operate in synchronization with the industry-standard 74 series logic family. This integrated circuit is a robust, versatile 8-stage shift-and-store bus register with three-state outputs, making it an ideal component for applications requiring serial-to-parallel data conversion with temporary data storage and serial data output capabilities.

Key Features

• Compatibility: Compatible with TTL levels, the 74HCT4094D is designed to interface with 5V systems, ensuring seamless integration into legacy and current logic circuit designs.
• Functionality: Features an 8-bit serial-in, parallel-out shift register that enables the conversion of serial data to parallel output form. This is complemented by a storage register and 3-state outputs, providing a flexible solution for data buffering and storage.
• Output Capability: Three-state outputs can deliver a high-current drive of +/-7.8mA at 5V, making it suitable for driving light loads or for interfacing with other logic families.
• Shift Register Clock (CP) and Output Register Clock (STR): Separate clock inputs for the shift and storage register allow for greater control over data manipulation and output timing.
• Output Enable (OE): The output enable input allows the user to place the eight outputs in either a normal logic state or a high-impedance state, facilitating the connection of multiple devices to a common bus without interference.
