The M74HC4050B1R is a high-speed CMOS hex non-inverting buffer integrated circuit, designed and manufactured by STMicroelectronics. This device features level-shifting capabilities, making it especially useful in applications where interfacing between different voltage domains is required. It is part of the HC (High-speed CMOS) family, known for combining the low power advantages of CMOS technology with the high-speed performance of bipolar transistors.

The M74HC4050B1R is capable of converting logic level signals from high to low, allowing devices that operate at higher voltages to communicate with those that operate at lower voltages. This is particularly important in mixed-voltage systems where signal integrity must be maintained across different logic levels.

This device is supplied in a 16-pin DIP (Dual In-line Package) referred to as the B1R package, which is suitable for through-hole mounting. This makes it convenient for prototyping and for use in applications where surface mount technology is not feasible or desired.

The M74HC4050B1R operates over a broad voltage range from 2V to 6V and features a high noise immunity characteristic of CMOS technology. It also boasts a low power consumption, with a typical quiescent current specification that ensures minimal power drain when the device is not actively switching.

Each buffer of the M74HC4050B1R has a separate input, and all six are non-inverting, providing a true representation of the input signal at the output. The device is characterized for operation from -55°C to +125°C, making it suitable for a wide range of industrial and automotive applications where reliability under extreme conditions is a necessity.

The M74HC4050B1R is a versatile component that can be used in a variety of electronic circuits, including but not limited to signal buffering, level translation, and voltage interfacing tasks. Its robust design and flexible power requirements make it a go-to choice for designers and engineers looking for a reliable solution in mixed-voltage environments.
