CD74HC4049E TI Hex Inverting Buffer/Converter | 16-PDIP | 2V-6V, High-Speed CMOS

Product Overview

The CD74HC4049E is a high-speed CMOS hex inverting buffer and logic-level converter from Texas Instruments. It features six independent inverters with high drive capability, making it suitable for driving high-capacitance loads or converting logic levels between different voltage domains. The device operates over a wide supply voltage range of 2V to 6V and is characterized for operation from -55°C to +125°C. Housed in a 16-pin PDIP package, it is ideal for through-hole PCB designs requiring robust logic buffering and level shifting.
