ON Semiconductor MC74VHC1G05DFT1G Inverter

The MC74VHC1G05DFT1G is a high-performance CMOS inverter with Schmitt-trigger inputs, manufactured by ON Semiconductor. This device is designed to meet the stringent requirements of today's advanced digital electronics. It features a single gate inverter configuration and is optimized for low power consumption while providing a high-speed interface between different voltage domains.

Constructed with silicon gate CMOS technology, the MC74VHC1G05DFT1G offers a robust and reliable solution for a wide range of applications. It provides a 5V tolerant input which can be interfaced to 5V logic levels even when operating at 3.3V. This level of versatility makes it suitable for interfacing with microcontrollers, logic conversion, and signal inversion in mixed 3.3V/5V systems.

The inverter's Schmitt-trigger input has hysteresis, which increases noise immunity and transforms slowly changing input signals into sharply defined jitter-free output signals, enhancing the device's performance in environments with electrical noise. This feature is particularly important in applications where signal integrity is critical.

The MC74VHC1G05DFT1G operates over a broad voltage range from 2.0V to 5.5V and is characterized for operation from -55°C to +125°C, making it suitable for use in industrial and automotive environments. Its low power dissipation and high noise immunity are in line with the requirements of JEDEC standard no. 7A.

This inverter comes in a compact SOT-353 (SC-70) package, which is ideal for space-constrained applications. The small footprint of the package allows for high-density mounting and is compatible with automated assembly processes, contributing to a reduction in overall production costs.

Key features of the MC74VHC1G05DFT1G include:

• High speed: t_PD = 3.9ns (typ.) at V_CC = 5V
• Low power dissipation: I_CC = 1µA (max.) at T_A = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min.)
• Power down protection provided on inputs
• Low noise: V_OLP = 0.8V (max.)
• Functional down to 2.0V
• Pin and function compatible with other standard logic families

Overall, the MC74VHC1G05DFT1G from ON Semiconductor is a versatile and reliable component that offers the performance and features needed for modern digital systems.
