The UPD74AC74GS-T1 is a Dual D-Type Flip-Flop with Set and Reset manufactured by NEC. This integrated circuit is a member of the 74AC series of advanced CMOS logic devices. It features two independent D-type flip-flops, each with its own data (D) input, clock (CLK) input, set (SD) input, reset (RD) input, and complementary outputs (Q and Q-bar). The device is designed for high-speed operation and low power consumption.

Applications

• Data storage and memory elements in digital systems.
• Shift registers and counters.
• Control circuits and state machines.
• Frequency dividers and timing circuits.
• Data synchronization and buffering.

Features

• Dual D-type flip-flops in a single package.
• Asynchronous set and reset inputs for flexible control.
• High-speed operation with typical propagation delay of a few nanoseconds.
• Low power consumption due to CMOS technology.
• Wide operating voltage range.
• Complementary outputs (Q and Q-bar) available for each flip-flop.

Benefits

• Versatile building block for various digital logic functions.
• Direct and immediate control over flip-flop state with set and reset inputs.
• Fast switching speeds enable high-performance system designs.
• Energy-efficient operation reduces power requirements and heat generation.
• Suitable for a wide range of applications due to its broad operating voltage range.
• Simplified circuit design with readily available complementary outputs.

Additional Details

The UPD74AC74GS-T1 is typically packaged in a small outline integrated circuit (SOIC) package, which allows for surface mounting on printed circuit boards. The device operates from a supply voltage typically between 2V and 6V. The set and reset inputs override the clock and data inputs, allowing the flip-flop to be directly set or reset to a specific state. Detailed electrical characteristics, timing diagrams, and pin configurations are available in the NEC datasheet for the UPD74AC74GS-T1.
