STMicroelectronics 74LVQ240 Octal Buffer/Line Driver

The 74LVQ240 from STMicroelectronics is a high-speed, low-voltage octal buffer and line driver designed to interface with 3.3V and 5V systems. This integrated circuit is part of the LVQ family, which is known for its ability to operate at low voltages while maintaining fast switching speeds and reduced power consumption.

Featuring eight non-inverting buffers with 3-state outputs, the 74LVQ240 is ideal for driving bus lines or buffer memory address registers. Its 3-state outputs ensure that multiple units can be connected to a bus without the risk of damaging the bus or the ICs connected to it.

The 74LVQ240 operates over a broad voltage range of 2.5V to 3.6V, which provides flexibility for interfacing with various logic levels. This makes it suitable for mixed-voltage applications and provides a bridge between incompatible logic circuits. The device also boasts a high drive capability, allowing it to drive heavy loads with minimal distortion and maximum efficiency.

Key features of the 74LVQ240 include:

• Octal non-inverting buffer/line driver with 3-state outputs
• Operates at a voltage range of 2.5V to 3.6V
• High-speed performance: t_PD = 3.8ns (max) at V_CC = 3.3V
• Power-down protection on inputs and outputs
• Low quiescent current: I_CC = 4µA (max)
• 24-pin thin shrink small outline package (TSSOP)

The device is also characterized by its power-down protection feature, which ensures that the inputs and outputs will be in a high-impedance state when the device is powered off. This avoids any potential damage that could be caused by residual voltage in the system.

The 74LVQ240 is packaged in a 24-pin TSSOP, providing a compact footprint for space-constrained applications. It is an excellent choice for implementing bus buffers in systems that require low-voltage operation and high-speed data transfer capabilities.

With its robust design and compatibility with industry-standard logic levels, the STMicroelectronics 74LVQ240 is a versatile component that enhances the reliability and performance of digital systems.
