SN74AHC126QPWRQ1 TI Buffer/Driver | 14-TSSOP | 2V-5.5V, 3-State

Product Overview

The SN74AHC126QPWRQ1 from Texas Instruments is a quad bus buffer gate with 3-state outputs, designed for automotive applications. It operates over a wide supply voltage range of 2V to 5.5V, making it suitable for interfacing with both 3.3V and 5V logic systems. The device features independent line drivers with 3-state outputs, which can be disabled to achieve high-impedance states for bus-oriented applications. Housed in a 14-pin TSSOP package, it is qualified to AEC-Q100 standards for automotive reliability.

Detailed Technical Specifications
