SN74ABT126NS TI Buffer/Driver | 4-Channel, 3-State, 4.5V-5.5V

Product Overview

The SN74ABT126NS is a high-performance quad bus buffer gate from Texas Instruments, featuring 3-state outputs and designed for 5V operation. It is part of the ABT (Advanced BiCMOS Technology) family, offering a perfect balance between speed and power consumption. The device is ideal for driving bus lines or buffering memory address registers, providing high drive capability (64mA sink/32mA source) while maintaining low static power dissipation. The 3-state outputs allow connection to a bus-oriented system without loading the bus when disabled.
