The TC74AC74FT is a dual D-type flip-flop with preset and clear from Toshiba Semiconductor and Storage. This device is fabricated using advanced CMOS technology to achieve high-speed performance with low power consumption. Each flip-flop has independent data, clock, preset, and clear inputs, making it versatile for a wide range of digital logic applications.

Applications

• Registers
• Counters
• Shift registers
• Memory storage elements
• Data synchronization

Features

• High-speed operation: tpd = 5.0 ns (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 µA (max) at VCC = 5V
• Operating voltage range: VCC = 2V to 6V
• Balanced propagation delays
• Symmetrical output drive capability
• ESD protection exceeds 2000V HBM
• Available in a small surface mount package (SOIC)

Benefits

• Improved system performance due to high-speed operation.
• Reduced power consumption leading to longer battery life in portable devices.
• Enhanced noise immunity due to wide operating voltage range.
• Simplified circuit design due to balanced propagation delays and symmetrical output drive.
• Increased reliability due to ESD protection.
• Space-saving design with the small surface mount package.

The TC74AC74FT is a positive-edge-triggered flip-flop. Information at the D input is transferred to the Q output on the positive-going edge of the clock pulse. The preset (PRE) and clear (CLR) inputs are asynchronous and operate independently of the clock input. When PRE is low, the Q output is set to high. When CLR is low, the Q output is set to low. Simultaneous low logic levels on the PRE and CLR inputs will force both Q and Q outputs high.

The device is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package suitable for surface mount technology. The operating temperature range is typically -40°C to +85°C, making it suitable for industrial applications.
