SN74LV126ADBR by Texas Instruments

The SN74LV126ADBR is a high-performance, quadruple bus buffer gate integrated circuit from the renowned manufacturer Texas Instruments. This device is specifically designed to provide optimal functionality in a wide range of electronic applications. The SN74LV126ADBR belongs to the 74LV family and is characterized by its low-voltage operation, making it suitable for interfacing with 3.3V logic levels.

Constructed with advanced silicon-gate CMOS technology, the SN74LV126ADBR offers a robust buffering solution with high-speed operation while maintaining low power consumption. Each of the four independent buffer gates in this IC is equipped with a 3-state output, which can be used to place the output in a high-impedance state. This feature is particularly useful for creating bus-oriented systems where multiple outputs can share a connection line without interference.

The SN74LV126ADBR comes in a compact SSOP (Shrink Small Outline Package) with 14 pins, designated by the suffix 'DBR' in its part number. This package type is ideal for space-constrained applications, as it minimizes the footprint on printed circuit boards (PCBs). The device's operating temperature range is from -40°C to +85°C, allowing for reliable performance in a variety of environmental conditions.

Key features of the SN74LV126ADBR include:

• Supply voltage range from 2V to 5.5V
• High drive capability with outputs that can sink or source up to 24mA at 3.3V
• Low input current of 1µA max, contributing to energy-efficient designs
• Typical tpd (propagation delay time) of 4.5ns, ensuring rapid signal processing
• Input and output over-voltage tolerance, providing protection against unexpected voltage spikes
• Latch-up performance that exceeds 250mA per JESD 17, guaranteeing robust operation

Applications for the SN74LV126ADBR are diverse, ranging from signal buffering in data communication systems to interfacing in microprocessor or microcontroller-based equipment. Its ability to function effectively at lower voltages also makes it an excellent choice for battery-operated devices and portable electronics.

Overall, the SN74LV126ADBR from Texas Instruments is a versatile and reliable component that offers designers a balance of power efficiency and high-speed performance, making it an essential part of modern electronic system design.
