Frequently Asked Questions
What is the function of the CD74HC244E-NG?
The CD74HC244E-NG is an octal (8-channel) non-inverting buffer and line driver with three-state outputs. It buffers logic signals for high-current bus driving and uses output enable control pins to place outputs in a high-impedance state, enabling multiple devices to share a single bus line in microprocessor and digital logic systems.
What supply voltage does the CD74HC244E-NG support?
The CD74HC244E-NG operates over a supply voltage range of 2 V to 6 V, typical of the HC (High-speed CMOS) logic family. This range provides compatibility with both 3.3 V and 5 V logic systems and allows direct interfacing with TTL-compatible inputs and CMOS logic devices without additional level-shifting circuitry.
What package does the CD74HC244E-NG use?
The CD74HC244E-NG is housed in a 20-pin DIP (Dual In-Line Package), as indicated by the E suffix in the Texas Instruments part number convention. The through-hole DIP package is suitable for breadboard prototyping, through-hole PCB assembly, and educational or development applications where socketed IC placement is preferred.
What are typical applications for the CD74HC244E-NG?
Common applications include address bus buffering in microprocessor systems, data bus line driving in memory interface circuits, I/O port expansion in embedded controllers, backplane signal distribution, and output port isolation in industrial automation equipment. The three-state capability allows multiple CD74HC244 devices to share a single bus under multiplexed control schemes.
What does the '-NG' suffix mean on the CD74HC244E-NG?
The '-NG' suffix in CD74HC244E-NG is a Texas Instruments product marking suffix designating a specific sub-version or date code variant of the device. It typically indicates product qualification or revision status. The E portion of the suffix designates the standard 20-pin DIP through-hole package used in this variant of the CD74HC244 octal buffer.
