SN74AHCT174DBR Hex D-Type Positive-Edge-Triggered Flip-Flops

The SN74AHCT174DBR from Texas Instruments is a high-performance, hex D-type flip-flop with clear functionality. This integrated circuit is part of the 'AHCT' family, which means it combines the speed of CMOS with the low power consumption of TTL, making it ideal for a wide range of applications, including those that require high speed and low power.

Each flip-flop has independent data, clock (CLK), and clear (CLR) inputs, with the Q outputs providing the respective flip-flop's current state. The positive-edge-triggered clock and direct clear inputs allow for synchronous control over the data, ensuring reliable operation even in fast-paced environments. This makes the SN74AHCT174DBR suitable for use in registers, counters, and control circuits where precise timing is crucial.

The device has a wide operating voltage range of 4.5V to 5.5V, which is typical for 5V systems, and it can interface directly with TTL levels, offering great flexibility in mixed-voltage environments. The SN74AHCT174DBR also features a balanced propagation delay and transition times, providing consistent performance across the entire voltage range.

Packaged in a DBR tape and reel, the device is designed for automated surface-mount assembly processes, which is a common requirement in high-volume production lines. The DBR suffix indicates the packaging type, which is important for manufacturers when ordering and handling these components.

The SN74AHCT174DBR offers the following key features:

• Hex D-type flip-flops with clear
