CD74HC4050M

CD74HC4050M Description

The CD74HC4050M from Texas Instruments is a high-speed CMOS hex non-inverting buffer designed for 2V to 6V supply voltage applications. Packaged in a 16-SOIC tube, this device features six independent buffers, each with a 1-bit configuration, making it ideal for signal conditioning, level shifting, and interfacing in digital systems. With a 5.2mA output current (both high and low), it ensures robust drive capability while maintaining low power consumption. The 74HC series offers compatibility with TTL levels, ensuring seamless integration in mixed-voltage environments.

CD74HC4050M Features

• Wide Voltage Range (2V–6V): Supports flexible power supply configurations, accommodating both low-voltage and standard CMOS/TTL logic levels.
• High Output Current (5.2mA): Capable of driving moderate loads, reducing the need for additional amplification stages.
• Non-Inverting Buffers: Preserves signal polarity, simplifying circuit design for unidirectional signal paths.
• Low Power Consumption: HC technology ensures minimal static power dissipation, ideal for battery-operated devices.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards for global deployment.
• Surface-Mount (SOIC-16): Compact footprint suits space-constrained PCB designs.

CD74HC4050M Applications

• Level Shifting: Bridges 3.3V and 5V logic systems in microcontrollers, FPGAs, and sensors.
• Signal Buffering: Isolates and strengthens signals in data buses, clock lines, and I/O ports.
• Industrial Control Systems: Enhances noise immunity in PLCs, motor drivers, and automation equipment.
• Consumer Electronics: Used in displays, memory interfaces, and peripheral connectivity (e.g., USB/UART).
• Automotive Electronics: Supports CAN/LIN bus interfaces due to robust ESD performance (though not explicitly rated for AEC-Q100).

Conclusion of CD74HC4050M

The CD74HC4050M excels in high-speed digital buffering with its low-power operation, wide voltage compatibility, and compact form factor. While marked as Last Time Buy, it remains a reliable choice for legacy designs or replacements in industrial, automotive, and consumer applications. Its non-inverting architecture and strong drive capability make it superior to basic logic buffers, particularly where signal integrity and minimal propagation delay are critical. Engineers should evaluate alternative active parts for new designs due to its end-of-life status.
