The CD74HCT74E is a high-speed CMOS Logic Dual Positive-Edge-Triggered D-Type Flip-Flop with Clear and Preset from Texas Instruments. This integrated circuit is part of the high-speed Si-gate CMOS family and is designed to operate in a broad range of applications, from industrial to commercial, where the need for high-speed and low power consumption is essential.
The device features two identical flip-flops with independent DATA, SET, RESET, and CLOCK inputs, and Q and Q̅ outputs. This configuration allows for the individual flip-flops to be used as two separate D-type flip-flops or connected together for toggle or JK flip-flop applications. The positive-edge trigger ensures that the flip-flops change state only at the rising edge of the clock signal, providing precise control over data synchronization.
The CD74HCT74E is characterized for operation from -55°C to 125°C, making it suitable for a wide range of environmental conditions. Its robust design includes a balanced propagation delay and transition times, which provides reliable, high-speed operation and reduced timing skew. The device is available in a standard 14-pin DIP package, making it easy to integrate into a variety of design layouts.
Key features of the CD74HCT74E include:
- High-speed CMOS technology
- Typical clock frequency of 50 MHz
- Balanced propagation delays and transition times
