Product Overview: 74LV4094D by NXP
The 74LV4094D is a high-performance, low-voltage 8-bit shift-and-store register product designed and manufactured by NXP Semiconductors. This integrated circuit is part of NXP's advanced 74LV family, which is known for its low-power consumption and high-speed operation. The 74LV4094D is specifically engineered to operate with a 3.3V power supply, making it suitable for battery-operated devices and low-power applications.
Key Features
- Voltage Range: The device operates on a voltage range of 2.0V to 5.5V, providing designers with flexibility in various power supply environments.
- Shift Register: It features an 8-bit serial-in/parallel-out shift register, which allows for the serial input of data and parallel output, enhancing the efficiency of data handling in digital systems.
- Edge-Triggered Clock: The shift register is driven by an edge-triggered clock (CP), which ensures precise timing for the shifting of data.
- Output Register: The device includes a storage register that provides a parallel 8-bit output (Q0 to Q7). This register is controlled by a separate output enable input (OE), which allows the user to control the availability of the output.
- Tri-State Outputs: The outputs are tri-state capable, which means they can be set to a high impedance state, effectively disconnecting the output from the circuit. This is particularly useful when multiple devices are connected to a common bus.
- Direct Clear Input: A direct clear input (CLR) allows for the immediate clearing of the shift register and storage register, thereby resetting the device's outputs.
Applications
The 74LV4094D is ideal for use in a wide range of applications, including:
- Serial-to-parallel data conversion
- Remote control holding registers
- LED and display drivers
- Data storage and transfer in computer and embedded systems
Quality and Reliability
NXP's commitment to quality ensures that the 74LV4094D meets the stringent requirements of the electronics industry. The device is available in a standard SO16 package, which is compatible with automated surface-mount assembly processes and suited for high-density PCB designs.
With its combination of low power, high speed, and versatile features, the 74LV4094D from NXP is an excellent choice for designers looking to implement reliable data storage and transfer mechanisms in their digital systems.
