The SN74LV125ATNSE4 is a quadruple bus buffer gate designed by Texas Instruments, which features 3-state outputs that are capable of driving 5.5 V with a 3.3 V or 2.7 V supply. This product belongs to the SN74LV family, which is known for its low-voltage operation and low power consumption, making it an ideal choice for interfacing with 5V systems in a mixed 3.3V/5V environment.

The device consists of four independent non-inverting buffer gates with 3-state outputs, which are designed to be employed in applications where buffer gates with high-speed and low-power operation are required. The 3-state outputs ensure that the device can be connected directly to a bus-structured system. They can be placed in a high-impedance state effectively disconnecting the output from the bus, which helps in sharing a common bus line among multiple devices without interference.

Key Features:

• Wide Operating Voltage Range of 2 V to 5.5 V
• Max tpd of 6.5 ns at 5 V
• Low Power Consumption, 20-µA Max ICC
• ±24-mA Output Drive at 3.3 V
• Inputs Accept Voltages to 5.5 V
• Latch-Up Performance Exceeds 250 mA Per JESD 17
• ESD Protection Exceeds JESD 22

The SN74LV125ATNSE4 is a versatile device that can be used in a variety of applications such as memory address drivers, buffer drivers, input/output port drivers, and line drivers. The device's high-drive outputs can sink/source 24 mA at 3.3 V, allowing it to drive multiple lines in bus-structured configurations.

This product is offered in a 14-pin TSSOP (Thin Shrink Small Outline Package) which is designed for space-saving on PCBs. Its robust design includes ESD protection that exceeds JESD 22, ensuring the device's reliability and longevity in demanding applications. Furthermore, the latch-up performance is compliant with the JESD 17 standard, providing additional safety against current overload.

Texas Instruments' SN74LV125ATNSE4 is a testament to the company's commitment to providing high-quality, reliable components for the electronics industry. Its combination of power efficiency, high speed, and robust protection features make it a smart choice for designers looking to optimize their high-speed digital systems.
