The TC74AC374F is an octal D-type flip-flop with three-state outputs manufactured by Toshiba Semiconductor and Storage. As a part of the Advanced CMOS (AC) series, it is known for its high-speed operation and low power consumption. This device contains eight D-type flip-flops with a common clock (CLK) input and three-state outputs. Data at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse. The three-state outputs allow for direct connection to a common bus. The TC74AC374F is commonly used in applications such as register files, memory address registers, and data bus interfacing. This device comes in a surface-mount package.

Applications:

• Register Files: Used to implement register files in digital systems.
• Memory Address Registers: Stores memory addresses for stable memory access.
• Data Bus Interfacing: Interfaces devices to a common data bus.
• Data Storage: Provides temporary storage of parallel data.
• Microprocessor Systems: Used in microprocessor-based systems for data handling and control.

Features:

• Octal D-Type Flip-Flops: Contains eight independent D-type flip-flops.
• Positive-Edge Triggered: Data is transferred on the rising edge of the clock signal.
• Three-State Outputs: Allows outputs to be placed in a high-impedance state.
• High-Speed Operation: Provides fast clock-to-output delays.
• Low Power Consumption: Operates with minimal power dissipation.
• Wide Operating Voltage: Functions over a broad voltage range.

The TC74AC374F contains eight D-type flip-flops. On the positive-going edge of the clock (CLK) input, the data present at the D inputs is transferred to the corresponding Q outputs. The output enable (OE) input controls the three-state outputs. When OE is low, the outputs are enabled and drive the latched data. When OE is high, the outputs are placed in a high-impedance state, allowing multiple devices to share a common bus. The device operates within a temperature range of -40°C to +85°C.
