74HC74N (Dual D-type flip-flop with set and reset-positive edge-trigger)

Overview

The 74HC74N is a high-speed dual D-type flip-flop IC from the 74HC family, featuring set and reset inputs. Each flip-flop is positive edge-triggered, meaning it captures the data input (D) on the rising edge of the clock pulse (CP). The device is designed for low-power consumption and high noise immunity, making it ideal for a wide range of digital applications. It includes clamp diodes that protect against electrostatic discharge and allow the use of current-limiting resistors, enhancing its robustness in real-world circuits.

Key Features

• Dual D-type flip-flops: Two independent flip-flops in a single 14-pin DIP package.
• Positive edge-triggered: Data is latched on the rising edge of the clock signal.
• Set and reset inputs: Asynchronous set (SD) and reset (RD) pins allow for immediate state control.
• High-speed operation: Propagation delay typically 13 ns at 5V supply.
• Low power consumption: CMOS technology ensures minimal power usage.
• Wide supply voltage range: Operates from 2V to 6V, compatible with TTL levels.
• Clamp diodes: Provide ESD protection and allow current limiting resistors.
