ON Semiconductor MC74VHC1G32DFT2G Single 2-Input OR Gate

The MC74VHC1G32DFT2G from ON Semiconductor is a high-performance, single 2-input OR gate fabricated with silicon gate CMOS technology. It achieves high-speed operation while maintaining the CMOS low power dissipation. This logic gate is designed for use in applications requiring a high-speed interface between devices operating at low voltage levels.

The device is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals, thanks to its high noise immunity and low propagation delay. The MC74VHC1G32DFT2G operates at a voltage range of 2V to 5.5V, making it versatile for interfacing with both 3.3V and 5V systems. This feature is particularly important for battery-operated and portable devices where power efficiency is critical.

Key features of the MC74VHC1G32DFT2G include:

• Logic Type: 2-Input OR Gate
• Supply Voltage Range: 2.0V to 5.5V
• High-Speed: t<sub>PD = 3.9ns (Typ) at V<sub>CC = 5V
• Low Power Dissipation: I<sub>CC = 2µA (Max) at T<sub>A = 25°C
• High Noise Immunity: V<sub>NIH = V<sub>NIL = 28% V<sub>CC (Min)
• Power Down Protection: Provided on inputs
• Pin and Function Compatibility: With other standard logic families
• Package: SC-88A (SOT-353)
• Lead-Free, Halogen-Free, and RoHS Compliant

Its small footprint SC-88A (SOT-353) package makes it ideal for space-constrained applications. The device also offers the advantage of power down protection on its inputs, which can prevent erroneous operation when the device is powered off. This protection feature ensures that the OR gate remains in a known state during power transitions.

The MC74VHC1G32DFT2G is also both lead-free and halogen-free, adhering to the RoHS directive, which is important for manufacturers who are environmentally conscious and aim to produce green products. Its compatibility with other standard logic families allows for easy integration into existing designs without the need for additional level shifting.

Overall, the MC74VHC1G32DFT2G is a reliable and efficient solution for designers looking to implement basic logic functions with high-speed and low-power requirements in their digital circuits.
