Frequently Asked Questions
What type of logic device is the SN74HC379N-00?
The SN74HC379N-00 is a 4-bit D-type flip-flop register belonging to the HC/UH high-speed CMOS logic family. It features a hold mode that allows the register to retain its stored data without clocking, making it useful in applications where data bus contention or selective update is required.
What is the maximum operating frequency of the SN74HC379N-00?
The SN74HC379N-00 operates at a maximum frequency of 20 MHz at nominal supply voltage with a 50 pF load capacitance. This makes it suitable for medium-speed digital logic applications including data registers, bus interfaces, and synchronous sequential logic designs in industrial and consumer electronics.
What package does the SN74HC379N-00 come in?
The SN74HC379N-00 is housed in a DIP-16 (Dual In-line Package, 16-pin) through-hole package, designated by JESD-30 code R-PDIP-T16. This package is ideal for breadboard prototyping, socketed PCB assemblies, and educational applications where easy insertion and removal of ICs is required.
How does the hold mode of the SN74HC379N-00 work?
The hold mode in the SN74HC379N-00 allows the flip-flop outputs to maintain their current state regardless of clock transitions, as long as the enable input is in the hold state. This feature is useful for selectively freezing data in a register during bus sharing or when synchronizing data across different clock domains in digital systems.
Is the SN74HC379N-00 compatible with other HC-family logic ICs?
Yes, the SN74HC379N-00 is fully compatible with the HC/UH (High-speed CMOS) logic family and is interoperable with TTL-level signal standards. It features a maximum output low current of 5.2 mA, making it capable of driving standard HC-family loads and enabling straightforward integration into existing digital logic designs using compatible ICs from Texas Instruments and other manufacturers.
