Frequently Asked Questions
What type of logic device is the CD74HCT73EE4?
The CD74HCT73EE4 is a dual J-K flip-flop from Texas Instruments in the HCT logic family. It provides two independent J-K flip-flop functions, each capable of operating as a toggle, set, or reset flip-flop depending on the J and K input states, making it a fundamental building block for counters, state machines, and clocked sequential logic circuits.
What is the maximum operating frequency of the CD74HCT73EE4?
The CD74HCT73EE4 operates at a maximum frequency of 20MHz (20,000,000 Hz) with a load capacitance of 50pF. This performance level is sufficient for most digital control, counter, and divider applications while the HCT family's TTL-compatible inputs ensure reliable clocking from standard 5V logic sources without additional interface circuitry.
What package does the CD74HCT73EE4 use?
The CD74HCT73EE4 is housed in a 14-pin plastic dual-in-line package (PDIP-14), JESD-30 code R-PDIP-T14. This through-hole DIP package is ideal for breadboard prototyping, socketed installations, and any application where easy manual insertion, replacement, or field service of the logic IC is required.
Can the CD74HCT73EE4 interface directly with TTL logic?
Yes, the CD74HCT73EE4 belongs to the HCT logic family, which is specifically designed with TTL-compatible input thresholds. This allows it to accept signals directly from TTL-level outputs (5V logic) while providing CMOS-level output swings, making it suitable for bridging or upgrading legacy TTL-based systems to more power-efficient CMOS designs without additional level-shifting components.
