Overview
The M74VHC1G126DFT1G, produced by ON Semiconductor, is a single gate noninverting 3-state buffer. This component is fabricated using advanced high-speed CMOS technology, which provides high speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation characteristic of CMOS devices. The device is available in tiny footprint packages such as SC-88A, SOT-353, TSOP-5, and SC-70, making it suitable for space-constrained applications. It features a buffered 3-state output that offers high noise immunity and stable output, and its input structure provides protection against voltages up to 7 V, regardless of the supply voltage, allowing it to interface 5 V circuits to 3 V circuits effectively.
