Product Overview: 74LV595PW by NXP Semiconductors
The 74LV595PW is a high-performance 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs, manufactured by NXP Semiconductors. This integrated circuit is part of the 74LV family, which signifies the use of a low-voltage interface that ensures compatibility with lower voltage systems. The device comes in a TSSOP16 (thin shrink small outline package) which is suitable for surface-mounted design applications.
Key Features
- Shift Register: The device incorporates an 8-bit serial-in shift register that allows serial input data to be shifted into the register on each rising edge of the clock signal.
- Storage Register: Following the shift register stage, there is an 8-bit storage register that holds the data before it is output to the data lines.
- 3-State Outputs: The 74LV595PW features 3-state outputs which provide high-impedance ('off') states, allowing for connection to a bus without interfering with other components.
- Edge-Triggered Clock: A positive-edge triggered clock (CP) and an output enable (OE) input control the state of the outputs.
- Wide Operating Voltage: It operates over a broad voltage range from 2.0V to 5.5V, making it versatile for interfacing with both 3.3V and 5V logic levels.
- Low Power Consumption: The 74LV595PW is designed for low power consumption, which is ideal for battery-operated and power-sensitive applications.
Applications
The 74LV595PW is suitable for a wide range of applications, particularly where there is a need to expand the number of outputs without increasing the number of I/O pins on a microcontroller. Common applications include:
- LED displays and LED matrix management
- Data acquisition systems
- Industrial control systems
- Relay control
- Serial-to-parallel data conversion
