MC74HC1G32DFT2G Product Summary

The MC74HC1G32DFT2G, manufactured by onsemi, is a single-channel, 2-input OR gate implemented in a compact SC-88A (SC-70-5/SOT-353) surface-mount package. Leveraging advanced CMOS technology, this device is tailored for applications demanding both space efficiency and reliable logic performance. Its high integration and minimal footprint make it ideal for dense circuit designs where board space is at a premium and consistent logic functions are critical to system operation.

Key Functional Features of the MC74HC1G32DFT2G

The MC74HC1G32DFT2G is specifically designed to deliver high-speed performance while maintaining low power consumption. Key attributes include typical propagation delays ($t_{PD}$) of 7 ns at a 5 V supply, and a maximum static supply current (ICC) of only 1 μA at room temperature, underscoring its suitability for battery-powered or energy-sensitive applications. The balanced propagation delay for both low-to-high and high-to-low transitions ensures symmetrical switching behavior—an essential requirement for timing-sensitive digital circuits. Notably, the device’s output stage supports balanced drive capabilities of ±2 mA, facilitating effective interfacing to a wide range of subsequent logic or load circuits. Engineered with robust internal buffering, the MC74HC1G32DFT2G achieves high noise immunity and output stability, critical for consistently accurate logic output in noisy environments.

Comprehensive Electrical and Timing Specifications of the MC74HC1G32DFT2G

Engineers benefit from the MC74HC1G32DFT2G’s optimized AC and DC electrical parameters. The typical propagation delay of 7 ns at 5 V allows for fast logic computation within modern high-speed embedded and control systems. The low typical input capacitance and minimal current draw further reduce dynamic and static power consumption, helping designers meet stringent efficiency targets. Furthermore, the device offers symmetrical output impedance and carefully matched rise and fall times, minimizing timing skew and signal integrity issues in high-density, high-speed architectures. The MC74HC1G32DFT2G’s high noise margins reinforce its resilience against signal disturbances—a crucial advantage in electrically noisy industrial or automotive environments. For automotive and demanding industrial markets, AEC-Q100 qualification and PPAP capability can be specified by selecting the appropriate -Q suffix version, ensuring reliability and certification compliance.
