Frequently Asked Questions
What is the maximum clock frequency of the CD74AC74EE4 and what load capacitance is this rated at?
The CD74AC74EE4 is rated for a maximum clock frequency of 90 MHz at a 50 pF load capacitance. This makes it suitable for high-speed synchronous logic designs in the AC CMOS family, where both speed and noise immunity are critical to reliable operation across the full supply voltage range of 2 V to 6 V.
How does CD74AC74EE4 differ from its 74HC74 counterpart in terms of speed and drive strength?
The CD74AC74EE4 (AC family) is significantly faster than 74HC74 equivalents, with 90 MHz max frequency compared to about 40 MHz for HC-family devices at similar supply voltages. The AC device also offers stronger output drive, with a maximum low-level output current of 12 mA, versus 4 mA typical for HC-family flip-flops.
For a through-hole prototype requiring two independent D flip-flops with direct set and clear control, why choose CD74AC74EE4?
CD74AC74EE4 provides 2 independent D-type flip-flops with separate active-low preset and clear inputs in a single 14-pin PDIP package, enabling direct insertion into a breadboard. Each channel can be independently set or reset without clocking, simplifying initialization logic in state machine and counter prototype designs.
