ON Semiconductor MC74VHC1G125DFT1G Single Bus Buffer Gate

The MC74VHC1G125DFT1G from ON Semiconductor is a high-performance, single bus buffer gate with 3-state output, designed to operate with a power supply range of 2V to 5.5V. This device is part of ON Semiconductor's VHC family, which is known for combining the low power dissipation of CMOS technology with the high speed of HC logic levels. The MC74VHC1G125DFT1G is ideal for interfacing between different voltage levels within a system and for driving heavy loads while maintaining signal integrity.

Constructed with silicon gate CMOS technology, it offers superior switching performance with high noise immunity and low power consumption. The 3-state output feature allows for connection to a bus-organized system without the need for external pull-up resistors. When the output enable (OE) input is high, the output is in a high impedance state, which prevents any potential conflict on the bus lines.

The MC74VHC1G125DFT1G is housed in a compact SOT-353 (SC-70) package, making it suitable for space-constrained applications. Its small footprint is beneficial for modern compact electronic assemblies such as smartphones, portable devices, and IoT gadgets. The device is also characterized for operation from -55°C to +125°C, ensuring reliable performance across a wide range of environmental conditions.

Key features of the MC74VHC1G125DFT1G include:

• High Speed: t_PD 4.5 ns (Typ) at V_CC = 5V
• Low Power Dissipation: I_CC = 2 μA (Max) at T_A = 25°C
• Power Down Protection Provided on Inputs and Outputs
• Low Noise: V_OLP = 0.8V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latch-Up Performance Exceeds 300 mA
• ESD Performance: HBM > 2000V; Machine Model > 200V

Whether it's for signal buffering, driving heavy loads, or interfacing with different logic levels, the MC74VHC1G125DFT1G is a versatile and reliable choice. ON Semiconductor's commitment to quality ensures that this buffer gate meets the stringent requirements of modern electronic systems, providing a robust and efficient solution for designers.
