onsemi MC74VHC1GT08DFT1: A High-Performance Single 2-Input AND Gate

The MC74VHC1GT08DFT1 from onsemi is a single 2-input AND gate fabricated with advanced silicon-gate CMOS technology. As part of the industry-standard VHC family, this IC is designed for use in systems where high-speed operation and low power dissipation are critical. It is a miniature but powerful logic function solution, ideal for a vast array of digital applications, from consumer electronics to complex industrial systems.

Housed in an ultra-compact SC-70-5 / SC-88A surface-mount package, this device is optimized for space-constrained PCB designs. Its tiny footprint makes it an excellent choice for modern portable devices like smartphones, tablets, and wearables, where every square millimeter of board space is valuable.

A key feature of this AND gate is its high-speed performance, with propagation delays (tPD) typically at 4.3 ns at 5V. This ensures swift signal processing, which is crucial for maintaining timing integrity in high-frequency circuits. Despite its speed, the device maintains very low static power consumption, drawing only a few microamps, which is a hallmark of CMOS technology and essential for battery-powered applications.

The MC74VHC1GT08DFT1 operates over a broad power supply voltage range of 2.0 V to 5.5 V. This flexibility allows it to interface seamlessly with both 3.3V and 5V logic levels, making it a versatile component for mixed-voltage system design. Furthermore, the outputs feature a balanced output drive, providing strong and symmetrical sourcing and sinking capabilities.

The device also incorporates robust ESD protection, exceeding 2000V per Human Body Model (HBM), which enhances its reliability and durability in demanding environments. Its noise immunity is significantly improved over older logic families, ensuring stable operation even in electrically noisy conditions.
