Key Features
- Dual independent positive-edge-triggered D flip-flops with asynchronous preset and clear for flexible control
- HC-family CMOS logic operating from 2 V to 6 V supply with 20 MHz maximum toggle frequency
- Complementary Q and Q-bar outputs on each element enabling direct T flip-flop or toggle implementations
- Tape-and-reel (T/R) packaging in 14-pin SOIC for high-volume automated PCB assembly
Applications
The CD74HC74MTE4 is widely used in digital state machines, frequency dividers, and data synchronization circuits across 3.3 V and 5 V embedded designs. Its dual independent flip-flops allow a single device to implement a 2-bit shift register or two separate edge-capture latches, reducing component count. The tape-and-reel format suits high-volume production runs in consumer electronics, industrial controllers, and communication equipment.

Frequently Asked Questions
At what maximum clock frequency can CD74HC74MTE4 reliably toggle at 5 V supply?
CD74HC74MTE4 is rated for a maximum clock frequency of 20 MHz at 5 V supply with a 50 pF load. At 3.3 V, the maximum frequency drops to approximately 8 MHz, so designers should verify timing margins when operating below the nominal 5 V rail.
How can a single CD74HC74MTE4 implement a divide-by-4 frequency counter?
Connect the Q-bar output of the first flip-flop to its own D input to create a divide-by-2 toggle stage outputting f/2. Feed that Q output into the D input of the second flip-flop clocked by the same source to get f/4 at the second Q, achieving divide-by-4 with just 2 pins of external wiring.
What output sink current does CD74HC74MTE4 provide, and what loads can it drive directly?
Each output of CD74HC74MTE4 sinks up to 5.2 mA at the specified test conditions with a 50 pF load. This is sufficient to directly drive standard CMOS gate inputs, indicator LEDs through a 680-ohm series resistor at 3.3 V, or MOSFET gate inputs with no additional buffer needed for low-speed switching up to 1 MHz.
Is CD74HC74MTE4 suitable for a battery-powered design running from a 2-cell alkaline supply?
Yes. The HC-family CD74HC74MTE4 operates from 2 V to 6 V, covering the 2.4 V to 3.0 V range of two AA alkaline cells at end-of-discharge. Quiescent supply current is below 80 µA at 5 V and even lower at reduced voltages, making it appropriate for power-sensitive portable or coin-cell-backed designs.
