Overview
The 74LVC2G240DP,125 from Nexperia USA Inc. is a dual inverting buffer/line driver with 3-state outputs. This component is designed to operate in a wide range of supply voltages from 1.65 V to 5.5 V, making it versatile for various applications. It features Schmitt trigger action at all inputs, which enhances the circuit's tolerance to slower input rise and fall times. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE, allowing the outputs to assume a high-impedance OFF-state when a HIGH level is applied to these pins. This device is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant input/output capability.
