The TC74HC74AFN is a high-speed CMOS dual D-type flip-flop with preset and clear from Toshiba Semiconductor and Storage. This device is fabricated with silicon gate CMOS technology, achieving high-speed operation similar to equivalent bipolar Schottky TTL devices while maintaining the low power consumption inherent to CMOS circuits. The TC74HC74AFN is suitable for use in a wide range of digital logic applications.

Applications:

• Registers
• Counters
• Control circuits
• Shift registers
• Memory storage units
• Data synchronizers

Features:

• High-Speed Operation: Propagation delay times are comparable to bipolar Schottky TTL, providing fast switching speeds.
• Low Power Dissipation: CMOS circuitry ensures minimal power consumption, making it suitable for battery-powered applications.
• Wide Operating Voltage Range: Operates from 2V to 6V.
• Dual D-Type Flip-Flops: Contains two independent D-type flip-flops in a single package, increasing design flexibility.
• Preset and Clear Inputs: Asynchronous preset (PRE) and clear (CLR) inputs allow for direct control over the flip-flop's output state, independent of the clock input.
• Positive-Edge Triggered: Data is transferred to the output on the positive-going transition of the clock pulse.
• JEDEC Standard No. 7A Compliant
• Operating Temperature Range: -40°C to +85°C

Benefits:

• Improved System Performance: High-speed operation reduces propagation delays, improving overall system performance.
• Reduced Power Consumption: Low power dissipation extends battery life in portable devices and reduces overall energy consumption.
• Enhanced Design Flexibility: Dual flip-flop configuration and preset/clear inputs provide greater flexibility in circuit design.

Additional Details:

The TC74HC74AFN comes in a SOP-14 (Small Outline Package) and is pin-compatible with standard TTL logic devices. Each flip-flop features individual data (D) inputs, clock (CLK) inputs, preset (PRE) inputs, clear (CLR) inputs, and complementary outputs (Q and Q\'). The asynchronous preset and clear inputs override the clock and data inputs, allowing for direct setting or resetting of the flip-flop output. The device is designed to be used in a wide variety of digital systems, where reliable high-speed operation and low power consumption are essential.
