The TC74LCX374FT is a high-performance, low-voltage octal D-type flip-flop with a 5V tolerant input manufactured by Toshiba Semiconductor and Storage. This device is designed for use in applications requiring high-speed data transfer and storage, such as in computers, telecommunications equipment, and other digital systems. It features a three-state output, allowing it to be easily connected to a bus.

Applications:

• High-speed data transfer
• Memory address latching
• Bus interface applications
• Microprocessor systems
• Digital signal processing

Features:

• Low-voltage operation: VCC = 2.0 to 3.6 V
• High-speed operation: tpd = 6.5 ns (max) at VCC = 3.3 V
• 5 V tolerant inputs
• Output impedance: |IOH| / IOL = 24 mA / 24 mA at VCC = 3.0 V
• Three-state outputs
• Package: TSSOP20

Benefits:

• Reduced power consumption: Low-voltage operation minimizes power dissipation.
• High-speed performance: Enables fast data processing and transfer.
• Easy interfacing: 5 V tolerant inputs allow direct connection to 5 V logic systems.
• Bus compatibility: Three-state outputs facilitate shared bus architectures.
• Compact size: TSSOP20 package saves board space.

The TC74LCX374FT features eight D-type flip-flops with a common clock (CK) and output enable (OE) input. When OE is low, the data on the D inputs are transferred to the outputs (Q) on the positive-going edge of the clock pulse. When OE is high, the outputs are in a high-impedance state. The device offers a significant speed improvement compared to older TTL logic families while maintaining low power consumption. The input and output characteristics make it suitable for mixed-voltage systems, where both 3.3 V and 5 V logic levels are present. The wide operating voltage range (2.0 to 3.6 V) provides flexibility in various applications.

This octal D-type flip-flop is available in a thin shrink small outline package (TSSOP), which is suitable for high-density board assembly. Its high output drive capability enables it to drive heavily loaded buses and transmission lines.
