The TC74VHC374FK is a high-speed silicon gate CMOS octal D-type flip-flop with 3-state outputs from Toshiba Semiconductor and Storage. This device is designed for use in high-performance applications where speed and low power consumption are critical. It features eight D-type flip-flops with a common clock and output enable, making it suitable for parallel data storage and transfer applications.

Applications:

• Register files
• Buffer registers
• Storage registers
• Address latches
• Data bus interface

Features:

• High-speed operation: tpd = 6.0 ns (typ.) at VCC = 5V
• Operating voltage range: 2 V to 5.5 V
• Low power consumption: ICC = 4 μA (max) at VCC = 5.5V
• 3-state outputs for bus-oriented applications
• Common clock and output enable inputs
• Positive edge-triggered D-type flip-flops
• Output drive capability: ±8 mA at VCC = 5V

Benefits:

• High-speed performance enables fast data storage and retrieval.
• Low power consumption reduces overall system power requirements.
• 3-state outputs allow multiple devices to share a common bus.
• Common clock and output enable simplify control logic.
• Wide operating voltage range supports various logic levels.

Additional Details:

The TC74VHC374FK is supplied in a VSSOP20 package. Data is clocked into the flip-flops on the positive-going edge of the clock pulse. The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled and reflect the data stored in the flip-flops. When OE is high, the outputs are in a high-impedance state. This allows multiple TC74VHC374FK devices to be connected to a common bus. The device operates over the temperature range of -40°C to +85°C.
