Description
This IC features eight non-inverting buffers arranged in two groups, each with its own enable input. The 3-state outputs can drive bus lines or buffer memory address registers, making it a versatile component in digital circuits. The 74LCX244MTC is commonly used in applications requiring high-speed data transfer and signal buffering, such as computer memory systems, telecommunications, and consumer electronics.
Packaged in a TSSOP (Thin Shrink Small Outline Package), it offers a compact footprint ideal for space-constrained applications. Its high-performance characteristics, low power consumption, and high noise immunity make the 74LCX244MTC a reliable choice for modern electronic designs.

Features
1. Low Voltage Operation: Operates with a voltage range of 2.0V to 3.6V, making it ideal for low-power applications.
2. High-Speed Performance: Provides fast switching speeds, typically with a propagation delay of 6.5 ns at 3.3V.
3. 3-State Outputs: Allows for bus-oriented applications, enabling multiple devices to share the same bus lines.
4. Input and Output Voltage Levels: TTL-compatible inputs and outputs ensure compatibility with standard TTL devices.
5. Drive Capability: Capable of driving up to 24 mA sink and source current at 3.0V.
6. Low Power Consumption: Features a quiescent current of just 10 µA max, which is ideal for battery-powered applications.
7. Improved Noise Margin: Offers better noise margin compared to standard logic levels.
8. ESD Protection: Provides robust ESD protection to enhance reliability.
This IC is suitable for applications requiring efficient signal buffering and line driving in digital systems.
Pinout
The pin configuration for the 74LCX244MTC is as follows:
- Pins 1 and 19: Output Enable (OE1, OE2)
- Pins 2, 3, 4, 5, 6, 7, 8, 9: Data inputs (1A1 to 1A4, 2A1 to 2A4)
- Pins 18, 17, 16, 15, 14, 13, 12, 11: Outputs (1Y1 to 1Y4, 2Y1 to 2Y4)
- Pin 10: Ground (GND)
- Pin 20: Positive Supply Voltage (Vcc)
The device features two groups of four buffers, each controlled by an output enable pin. When the output enable is high, the outputs are disabled (high impedance). When low, the outputs follow the input. This configuration allows for efficient data management and transmission within digital systems.
