Overview
The 74HCT125PW/S400118, manufactured by NXP USA Inc., is a quad buffer/line driver integrated circuit. It belongs to the 74HCT series and is designed to operate within a wide supply voltage range of 4.5 V to 5.5 V. This device is packaged in a 14-pin Thin Shrink Small Outline Package (TSSOP) and is suitable for surface mount applications. The 74HCT125PW/S400118 features 3-state outputs controlled by output enable inputs, allowing the outputs to assume a high impedance OFF-state when the output enable input is HIGH. This IC is part of the Logic - Buffers, Drivers, Receivers, Transceivers category and is known for its CMOS low power dissipation and high noise immunity.
