SN74LVC2244APWR

The SN74LVC2244APWR is a high-speed, low-voltage CMOS buffer/driver designed by Texas Instruments. It is part of the LVC family of logic devices, which are known for their low power consumption and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

The SN74LVC2244APWR is a dual buffer/driver with 3-state outputs, meaning it can drive signals in three different states: high, low, and high-impedance (floating). This makes it particularly useful in applications where multiple devices need to share a common bus without interfering with each other.

Key Features:

• Voltage Range: The device operates over a wide supply voltage range, typically from 1.65V to 5.5V, making it suitable for various low-voltage applications.
• High-Speed Operation: It can achieve propagation delays as low as 3.5 ns at 3.3V, allowing for fast signal transmission.
• Low Power Consumption: The device features low static and dynamic power consumption, which is essential for battery-operated devices and energy-efficient designs.
• Input/Output Compatibility: The SN74LVC2244APWR is compatible with TTL (Transistor-Transistor Logic) levels, allowing it to interface with a variety of logic families.
• 3-State Outputs: The outputs can be enabled or disabled, allowing for flexible bus configurations and reducing the risk of signal contention.
• Temperature Range: It operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

Pin Configuration:

The SN74LVC2244APWR is available in a TSSOP (Thin Shrink Small Outline Package) with 14 pins. The pin configuration includes:

• Inputs: Two sets of inputs (A1, A2, B1, B2) for the two buffer/driver sections.
• Outputs: Corresponding outputs (Y1, Y2, Z1, Z2) for each input.
• Enable Pins: Each buffer has an enable pin (OE1, OE2) that controls the output state.
• Power and Ground: VCC pin for power supply and GND pin for ground connection.

Applications:

The SN74LVC2244APWR is widely used in various applications, including:

• Data communication systems
• Bus-oriented applications
• Signal buffering in digital circuits
• Level shifting between different voltage domains
• General-purpose logic applications
