Overview
The 74ALVC125BQ,115 is a quad non-inverting buffer/line driver with 3-state outputs, manufactured by Nexperia (previously part of NXP Semiconductors). This device is designed for low-power, low-voltage applications and is superior to most advanced CMOS compatible TTL families. It features Schmitt trigger action on all inputs, making it tolerant of slow rise and fall times. The 3-state outputs are controlled by the output enable input (nOE), allowing the outputs to assume a high-impedance OFF-state when nOE is HIGH.
