Key Features
- 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs.
- Separate clocks for the shift and storage registers.
- Serial input (D) and two serial outputs (QS1 and QS2) for cascading.
- Data shifted on LOW-to-HIGH transitions of the CP input.
- Data transfer from shift register to storage register when STR input is HIGH.
- Output enable input (OE) controls the output state; LOW on OE causes outputs to assume a high-impedance OFF-state.
- Inputs include clamp diodes for voltage protection.
- Low-power dissipation and ESD protection.
- Complies with JEDEC standard JESD7A for CMOS level inputs.
Applications
- Serial-to-parallel data conversion.

- Various applications across automotive, industrial, power, computing, consumer, mobile, and wearables industries.
Q & A
- What is the primary function of the 74HC4094D,653?
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 type of package does the 74HC4094D,653 come in?
The 74HC4094D,653 comes in a 16-SOIC (SOT109-1) package.
- What is the supply voltage for the 74HC4094D,653?
The supply voltage is 5 V.
- What is the temperature range for the 74HC4094D,653?
The temperature range is -40°C to +125°C.
- Does the 74HC4094D,653 have ESD protection?
- How does data transfer occur between the shift and storage registers?
Data is transferred from the shift register to the storage register when the STR input is HIGH.
- What is the role of the OE input?
The OE input controls the output state; a LOW on OE causes the outputs to assume a high-impedance OFF-state.
- Is the 74HC4094D,653 RoHS compliant?
- What are some common applications of the 74HC4094D,653?
- Where can I purchase the 74HC4094D,653?
- What is the significance of QS1 and QS2 outputs in the 74HC4094D,653?
The QS1 and QS2 outputs enable cascading of the shift registers, with QS1 providing data on LOW-to-HIGH transitions of the CP input and QS2 providing data on the next HIGH-to-LOW transition of the CP input.
