Overview
The 74LVC3G34DC is a high-performance, low-power, low-voltage, Si-gate CMOS triple buffer device manufactured by Nexperia (previously part of NXP Semiconductors). This device is designed to operate in mixed 3.3 V and 5 V environments, making it an ideal choice for applications requiring voltage translation. The 74LVC3G34DC features Schmitt-trigger inputs, which enhance noise immunity and tolerance to slower input rise and fall times. It is fully specified for partial power-down applications using IOFF circuitry, preventing backflow current when the device is powered down.
