SN74ABT125DBR TI Buffer/Driver | 14-SSOP | 4-ch, 3-State, 32mA

Product Overview

The SN74ABT125DBR is a quad bus buffer gate with 3-state outputs from Texas Instruments, designed for high-speed signal buffering and driving in digital systems. Housed in a compact 14-SSOP package, it features four independent buffer gates with non-inverting outputs, each controlled by an output enable (OE) input. The device operates over a wide supply voltage range of 4.5V to 5.5V and offers high drive capability of up to 32mA sink/source, making it suitable for driving heavy capacitive loads or multiple inputs. Its 3-state outputs allow for bus-oriented applications where multiple outputs can share a common line.
