Key Features
- Separate Clocks: The device has separate clocks for the shift and storage registers, allowing for independent control over data shifting and storage.
- Cascading Capability: The component features two serial outputs (QS1 and QS2) to enable cascading, making it suitable for complex data handling applications.
- 3-State Outputs: The outputs can be in high, low, or high-impedance state, controlled by the output enable input (OE).
- Clamp Diodes on Inputs: Inputs include clamp diodes to protect against voltage spikes and ensure robust operation.
- Flexible Data Handling: Data is shifted on the LOW-to-HIGH transitions of the CP input, and the same data is available at QS2 on the next HIGH-to-LOW transition of the CP input.
Applications
The HEF4094BTS,118 is versatile and can be used in a variety of applications across different industries, including:
- Automotive Systems: For data processing and storage in automotive electronics.
- Industrial Control Systems: In control circuits and data processing units.

Q & A
- What is the primary function of the HEF4094BTS,118?
The primary function is to act as an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- What package type does the HEF4094BTS,118 come in?
The component comes in a TSSOP16 (SOT403-1) package.
- How does the device handle cascading?
The device features two serial outputs (QS1 and QS2) to enable cascading, allowing for the connection of multiple shift registers.
- What is the purpose of the OE input?
The OE (Output Enable) input controls the state of the outputs, allowing them to be in high, low, or high-impedance state.
- Is the HEF4094BTS,118 RoHS compliant?
Yes, the component is RoHS compliant.
- How is data shifted in the shift register?
Data is shifted on the LOW-to-HIGH transitions of the CP input.
- What is the role of the STR input?
The STR input is used to transfer data from the shift register to the storage register when it is HIGH.
- Can the outputs be disabled?
Yes, the outputs can be disabled by setting the OE input to LOW, causing the outputs to assume a high-impedance OFF-state.
- What industries can this component be used in?
