SN74LV125ATNSR Quad Bus Buffer Gate with 3-State Outputs

The SN74LV125ATNSR from Texas Instruments is a high-performance, quadruple bus buffer gate featuring 3-state outputs that is designed to operate from 2 V to 5.5 V. This device is optimized for use in a wide variety of applications, including memory address drivers, clock drivers, and bus-oriented transmitters/receivers.

With its low-voltage operation, the SN74LV125ATNSR is particularly suitable for interfacing with 5V TTL logic in mixed-voltage systems. The low-power consumption of this device makes it ideal for battery-operated and portable electronics where power efficiency is a critical factor.

The 3-state outputs are controlled by the output-enable (OE) inputs. When OE is low, the outputs are in the active high or low state. When OE is high, the outputs are in the high-impedance state, which effectively disconnects the outputs from the bus. This allows for the connection of multiple outputs to the same bus without the risk of damaging the drivers or the bus.

The SN74LV125ATNSR is available in a compact 14-pin NSOIC package, which makes it easy to integrate into space-constrained designs. The NSOIC package also offers improved thermal performance, which is beneficial in applications where the device may be subject to high ambient temperatures.

Key features of the SN74LV125ATNSR include:

• Support for 2 V to 5.5 V V_CC operation.
• Maximum t_pd of 6.5 ns at 5 V.
• Low power consumption: I_CC of 20 μA maximum.
• ±24-mA output drive at 3.3 V.
• Latch-up performance exceeds 250 mA per JESD 17.
• ESD protection exceeds JESD 22.

The device's robust construction ensures that it can withstand the rigors of industrial environments, while its ESD protection and latch-up performance make it reliable in the face of electrostatic discharges and other potentially damaging events. Whether you're designing a new system or upgrading an existing one, the SN74LV125ATNSR is a versatile component that will enhance the reliability and functionality of your electronic designs.
