Description
The 74HC4094D from Nexperia is a high-speed, 8-stage serial-in/serial-or-parallel-out shift register. It integrates an 8-bit shift register with a storage register and 3-state output buffers. This architecture allows for versatile data handling, where both the shift and storage registers operate on separate clocks. The device includes a serial input (D) and dual serial outputs (QS1 and QS2) to facilitate easy cascading of multiple units, supporting both fast and slow clock edge transitions.
Data stored in the shift register is transferred to the storage register when the STR (Strobe) input is HIGH. The stored data is presented at the outputs when the Output Enable (OE) input is HIGH; when OE is LOW, the outputs enter a high-impedance (OFF) state. The 74HC4094D is widely used in applications such as serial-to-parallel data conversion, remote control holding registers, and complex bus management systems.
Key Features
- 8-Bit Versatility: 8-stage shift register with integrated storage and 3-state parallel outputs.
- Flexible Cascading: Features dual serial outputs (QS1 and QS2) for seamless cascading regardless of clock edge speed.
- Independent Clocks: Separate inputs for shift and storage registers provide superior control.
- Robust Power: Wide supply voltage operating range of 2V to 6V.
- High Reliability: Complies with JEDEC standard JESD 7A and includes built-in ESD protection.
- Wide Temp Range: Industrial-grade performance from -40°C to +125°C.
Applications
- Data Conversion: Efficient serial-to-parallel interface conversion.
- Remote Control: Used as a holding register for command and control signals.
- Bus Expansion: Ideal for increasing the number of outputs on microcontrollers or PLCs.
- LED & Display Drivers: Controlling multiple indicators or segments using limited pins.
