Details
MM74C74N DescriptionThe MM74C74 dual D-type flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. Each flip-flop has independent data, preset, clear and clock inputs and Q and Q outputs. The logic level present at the data input is transferred to the output during the positive going transition of the clock pulse. Preset or clear is independent of the clock and accomplished by a low level at the preset or clear input.MM74C74N Features■ Supply voltage range: 3V to 15V■ Tenth power TTL compatible: Drive 2 LPT2L loads■ High noise immunity: 0.45 VCC (typ.)■ Low power: 50 nW (typ.)■ Medium speed operation: 10 MHz (typ.) with 10V supplyMM74C74N Applications• Automotive• Data terminals• Instrumentation• Medical electronics• Alarm system• Industrial electronics• Remote metering• Computers

FAQs
What is MM74C74N?
The MM74C74N is a dual D-type positive edge-triggered flip-flop integrated circuit (IC) designed by Fairchild Semiconductor. It is used for storing and transferring binary data in digital systems, and it is commonly employed in clocked sequential logic circuits, counters, and delay circuits.
How Does MM74C74N Work?
The MM74C74N works by capturing and storing binary data at its inputs on the rising edge of the clock signal. Each flip-flop within the IC can operate independently, enabling the storage and transfer of two separate binary bits. It is well-suited for applications where synchronized data transfers and signal timing are essential.
How Many Pins does MM74C74N have and What are the Functions of the Pinout Configuration?
The MM74C74N is housed in a 14-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- 1Q, 2Q: Outputs of the two flip-flops.
- 1D, 2D: Data inputs for the two flip-flops.
- 1CK, 2CK: Clock inputs for the two flip-flops.
- 1PR, 2PR: Preset inputs for the two flip-flops.
- 1CLR, 2CLR: Clear inputs for the two flip-flops.
- GND: Ground pin.
- VCC: Positive power supply pin.
What are the Pros and Cons of MM74C74N?
Pros:
- Dual Flip-Flops: Provides two independent D-type flip-flops in a single IC package.
- Positive Edge-Triggered: Enables synchronized data capture on the rising edge of the clock signal.
- Simple Interface: Straightforward pinout configuration for easy integration into digital circuits.
- DIP Package: DIP packaging allows for easy prototyping and breadboarding.
- Wide Operating Voltage Range: Capable of operating over a wide voltage supply range.
Cons:
- Manual Reset: Requires external circuitry if manual reset functionality is needed.
- Limited Functionality: May not be suitable for applications requiring more advanced sequential logic functions.
- Obsolete: Availability may be limited due to the IC being older and potentially obsolete.
Are There Any Equivalents/Alternatives to MM74C74N for Recommendation?
- The SN74LS74A from Texas Instruments is a similar dual D-type flip-flop IC.
- Alternatives to the MM74C74N include the CD74HC74 from Texas Instruments and the HCF4075B from STMicroelectronics.
