Key Features
- 6 independent non-inverting buffer channels in a single PDIP-16 package for compact logic fan-out designs
- 18 mA output sink/source current per channel enables direct drive of LEDs and small signal loads without extra driver stages
- 50 pF rated load capacitance supports high-speed logic line driving at frequencies common in 4000-series CMOS systems
- Wide supply voltage range compatible with 3 V to 15 V CMOS systems for cross-voltage level interfacing
Applications
The CD4050BEE4 is commonly used as a logic-level buffer and voltage-level translator in mixed-voltage embedded systems where signals must cross from a higher-voltage CMOS domain to a lower-voltage TTL or microcontroller input. Its 6 channels make it efficient for parallel bus buffering, clock distribution, and fan-out from a single-output signal to multiple destination nodes. The PDIP-16 package is well-suited for breadboard prototyping and through-hole PCB designs in hobbyist and industrial control applications.

Frequently Asked Questions
How does the CD4050BEE4 perform level translation from a 12 V CMOS signal down to a 5 V logic input?
The CD4050BEE4 is designed specifically for high-to-low level shifting: the input can accept voltages up to the supply rail of the driving source (e.g., 12 V) while the output swings relative to the CD4050's own VDD. By powering the CD4050BEE4 from 5 V and feeding a 12 V CMOS signal into its input, the output produces a 5 V-compatible logic signal. This avoids the risk of exceeding the 5 V microcontroller's maximum input voltage of typically 5.5 V.
Can the CD4050BEE4 drive multiple TTL logic inputs simultaneously from a single CMOS source?
Yes. Each of the 6 buffer channels provides up to 18 mA output current, enough to drive at least 10 standard TTL inputs which draw approximately 1.6 mA each. For a parallel 8-bit data bus where every line fans out to 2 TTL loads at 1.6 mA each, the CD4050BEE4 handles 6 of those lines comfortably within its 18 mA per-channel rating, requiring at most 2 ICs for a full 8-bit interface.
What is the propagation delay and switching speed of the CD4050BEE4 at 5 V supply?
At a 5 V supply with a 50 pF load capacitance, the CD4050BEE4 exhibits a typical propagation delay of approximately 60 ns to 125 ns, depending on operating temperature and exact supply voltage. This speed is adequate for 4000-series CMOS systems clocked below 8 MHz. For faster logic at 5 V, designers should consider 74HC or 74ACT series buffers which achieve propagation delays below 10 ns.
For a through-hole prototype, how does the PDIP-16 package of the CD4050BEE4 simplify development compared to SMT alternatives?
The PDIP-16 package has 16 pins on a 0.1-inch (2.54 mm) pitch that plugs directly into a standard solderless breadboard or through-hole PCB without adapters. Each pin row spans 0.3 inches (7.62 mm), fitting any standard 0.3-inch DIP socket. This eliminates the soldering iron and magnification tools required for SOIC-16 or TSSOP packages with 1.27 mm or 0.65 mm pitch, making the CD4050BEE4 PDIP-16 the preferred choice for rapid prototyping and educational lab work.
