The UPD74HC74GS-E2 is a dual D-type flip-flop with set and reset capabilities, manufactured by NEC. Each flip-flop features independent data, clock, set, and reset inputs. The device is designed for a wide range of applications requiring data storage and manipulation.

Applications

• Data Storage: Storing single bits of data in digital systems.
• Shift Registers: Constructing shift registers for serial-to-parallel or parallel-to-serial data conversion.
• Counters: Implementing various types of counters, such as ripple counters or synchronous counters.
• Frequency Dividers: Dividing input frequencies by a factor of two.
• Control Circuits: Implementing control logic in digital systems.

Features

• Dual D-Type Flip-Flop: Contains two independent D-type flip-flops in a single package.
• Set and Reset Inputs: Allows the flip-flops to be asynchronously set or reset.
• Positive-Edge Triggered Clock: The flip-flops trigger on the positive-going edge of the clock input.
• CMOS Technology: Provides high noise immunity and low static power dissipation.
• Wide Operating Voltage Range: Operates over a wide range of supply voltages (2V to 6V).
• Low Power Consumption: Consumes minimal power, making it suitable for battery-powered applications.

Benefits

• Versatile Data Storage: Can be used for a wide variety of data storage and manipulation applications.
• Asynchronous Set and Reset: Provides flexibility in controlling the state of the flip-flops.
• Energy Efficiency: Low power consumption contributes to energy savings.
• Reliable Operation: CMOS technology ensures reliable operation in noisy environments.
• Simplified Circuit Design: Simplifies the design of sequential logic circuits.

Additional Details

The UPD74HC74GS-E2 operates by transferring the data present at the D input to the Q output on the positive-going edge of the clock input. The set and reset inputs override the clock and data inputs, allowing the flip-flop to be asynchronously set to a high level (Q=1) or reset to a low level (Q=0). Simultaneous assertion of both the set and reset inputs is not recommended.

This device is commonly available in a SOIC (Small Outline Integrated Circuit) package.
