onsemi MC74HC1G08DFT1G: Single 2-Input AND Gate Datasheet and Application Overview

The MC74HC1G08DFT1G from onsemi is a single 2-input AND gate integrated circuit belonging to the high-speed CMOS logic family. Housed in an ultra-compact SC-70-5 / SC-88A package, this device is engineered for applications where minimal board space and low power consumption are critical design constraints. It operates across a broad voltage range from 2.0 V to 6.0 V, making it compatible with various logic levels and suitable for both 3.3V and 5V systems.

This AND gate performs the fundamental logical function where the output Y is HIGH only when both inputs A and B are HIGH (Y = A • B). The HC1G08 leverages advanced silicon-gate CMOS technology, achieving the low power consumption typical of CMOS chips while providing high-speed operation comparable to LSTTL logic. It features robust output drive capability, with the ability to source or sink up to 4 mA, and incorporates inputs with Schmitt triggers, which provide improved noise immunity and cleaner output signal transitions.

Key electrical characteristics highlighted in the datasheet include a high noise immunity, a low quiescent current (ICC), and a fast propagation delay (tPD), ensuring efficient and reliable performance in high-speed switching environments. The device is also characterized for operation from -40°C to +125°C, making it robust enough for automotive and industrial applications.

Typical applications for the MC74HC1G08DFT1G are vast due to its fundamental role in digital logic. It is commonly used in:

Portable and Battery-Powered Devices: Due to its low power consumption and tiny footprint.

Signal Gating: Enabling or disabling the passage of a digital signal based on a control input.
