SN74LVC112AD

The SN74LVC112AD is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the LVC family of logic devices, which are designed to operate with low voltage and low power consumption while maintaining high-speed performance. Here’s a detailed description of its features and specifications:

General Features:

• Type: Dual D-type Flip-Flop
• Technology: CMOS (Complementary Metal-Oxide-Semiconductor)
• Supply Voltage: Operates from a supply voltage range of 1.65V to 5.5V, making it suitable for a variety of applications, including battery-powered devices.
• Input Voltage Levels: Compatible with both TTL (Transistor-Transistor Logic) and CMOS logic levels, allowing for versatile interfacing with other logic families.
• Propagation Delay: Offers fast propagation delays, typically around 3.5 ns at 3.3V, which is beneficial for high-speed applications.

Pin Configuration:

The SN74LVC112AD typically comes in a 14-pin package (DIP, SOIC, or TSSOP), with the following key pins:

• D1, D2: Data inputs for the two flip-flops.
• CLK1, CLK2: Clock inputs for the two flip-flops, which trigger the state change on the rising edge.
• CLR1, CLR2: Asynchronous clear inputs that reset the flip-flops to a low state when activated.
• PRE1, PRE2: Asynchronous preset inputs that set the flip-flops to a high state when activated.
• Q1, Q2: Outputs of the two flip-flops, reflecting the stored data.
• Q1', Q2': Inverted outputs of the two flip-flops.

Functional Characteristics:

• Edge-Triggered: The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal.
• Asynchronous Control: The clear and preset functions allow for immediate control of the output states, independent of the clock signal.
• Low Power Consumption: Designed for low power operation, making it suitable for portable and battery-operated devices.

The SN74LVC112AD is widely used in various applications, including:

• Data storage and transfer in digital circuits.
• Frequency division and signal synchronization.
• State machines and control logic in embedded systems.
• Temporary data storage in microcontroller applications.

Package Options:

The device is available in multiple package types, including:

• DIP (Dual In-line Package): For through-hole mounting.
• SOIC (Small Outline Integrated Circuit): For surface mounting with a smaller footprint.
• TSSOP (Thin Shrink Small Outline Package): For applications requiring even more compact designs.

Electrical Characteristics:

• Input/Output Voltage Levels: The device can accept input voltages as low as 0.3V and as high as the supply voltage, ensuring compatibility with various logic levels.
• Output Drive Capability: Capable of driving standard loads, making it suitable for interfacing with other digital components.

In summary, the SN74LVC112AD from Texas Instruments is a versatile and efficient dual D-type flip-flop that combines low power consumption with high-speed performance, making it an excellent choice for a wide range of digital applications.
