SN74LS09DR

The SN74LS09DR is a quad 2-input NAND gate integrated circuit (IC) manufactured by Texas Instruments, part of the 74LS (Low Power Schottky) series. This IC is designed for high-speed digital logic applications and is widely used in various electronic circuits due to its reliability and performance.

Key Features:

1. Quad 2-Input NAND Gates: The SN74LS09DR contains four independent 2-input NAND gates. Each gate can perform the NAND operation, which outputs a low signal only when both inputs are high.

2. Low Power Consumption: As part of the Low Power Schottky family, the SN74LS09DR is designed to operate with lower power consumption compared to standard TTL (Transistor-Transistor Logic) devices, making it suitable for battery-operated devices and applications where power efficiency is critical.

3. High Speed: The device operates at a maximum propagation delay of around 10 nanoseconds, allowing for fast switching and high-speed operation in digital circuits.

4. Wide Supply Voltage Range: The SN74LS09DR typically operates with a supply voltage (Vcc) ranging from 4.75V to 5.25V, making it compatible with standard TTL logic levels.

5. Input and Output Characteristics: The inputs are TTL-compatible, meaning they can accept standard TTL logic levels. The output can drive multiple TTL inputs, providing flexibility in circuit design.

6. Temperature Range: The device is rated for operation over a temperature range of -40°C to +85°C, making it suitable for industrial and automotive applications.

7. Pin Configuration: The SN74LS09DR is available in a 14-pin Dual In-Line Package (DIP) or a surface-mount package (SOIC), with each pin serving a specific function related to the NAND gates and power supply.

8. Applications: Common applications include digital logic circuits, data processing, signal conditioning, and any application requiring logic gate functionality.
