STMicroelectronics 74VHCT125ATTR Quad Buffer/Line Driver
The 74VHCT125ATTR is a high-speed CMOS device from STMicroelectronics, designed to meet the requirements of high-performance electronic systems. This integrated circuit features four independent non-inverting buffer/line drivers with 3-state outputs, which makes it an excellent choice for driving bus lines or buffer memory address registers.
Each buffer has its own output enable (OE) pin, which when held high, puts the output in a high impedance state. This feature is essential for interfacing with bus lines in a shared environment, allowing multiple devices to communicate without interference. When the OE is low, the buffer conducts and the output reflects the input signal with high fidelity.
The 74VHCT125ATTR operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL levels, while offering the benefits of CMOS technology, such as lower power consumption and reduced noise. This balance of compatibility and performance ensures that the device can be used in mixed-technology systems without compromising on power efficiency or speed.
This quad buffer/line driver comes in a TSSOP-14 package, which is a space-saving option for PCBs where space is at a premium. The small footprint does not detract from the device's performance, which includes fast switching times and a high degree of noise immunity.
Key features of the 74VHCT125ATTR include:
- High-speed: Typical t<sub>pd of 8.5ns at V<sub>CC = 5V
- Low power dissipation: I<sub>CC is 2μA (max) at TA = 25°C
- Power down protection is provided on all inputs and outputs
- Pin and function compatible with 74 series logic
- Multiple package options for design flexibility
With its robust design and reliable performance, the 74VHCT125ATTR is suitable for a wide range of applications, including logic level shifting, driving heavy loads, and as a control interface for peripheral devices. Whether used in industrial control systems, consumer electronics, or computer peripherals, this device from STMicroelectronics provides a dependable solution for digital buffering requirements.
