Product Overview: 74LVT244APW,118

The 74LVT244APW,118 is a high-performance, low-voltage, octal buffer/line driver with 3-state outputs designed and manufactured by NXP Semiconductors. This integrated circuit is part of the LVT family, which stands for Low-Voltage Technology, and is specifically engineered to operate at a nominal voltage of 3.3V, making it suitable for interfacing with 3.3V logic levels in a wide range of applications.

Constructed with an advanced silicon-gate CMOS technology, the 74LVT244APW,118 offers the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It is packaged in a 20-lead thin shrink small outline package (TSSOP), denoted by the 'PW' in its part number, providing a compact footprint that is ideal for space-constrained applications.

The device features eight non-inverting buffers with 3-state outputs, which can be used as line drivers for data transmission. The 3-state outputs ensure that the device can be connected directly to a bus-structured system. When the output enable (OE) input is high, the outputs are in a high-impedance state, which effectively disconnects the outputs from the bus. This allows for bidirectional data flow in a bus-oriented system without the risk of data contention.

Key specifications of the 74LVT244APW,118 include:

• Supply voltage (Vcc) ranging from 2.7V to 3.6V
• High-impedance off-state outputs for bus-oriented applications
• Power-off disable outputs permit "live insertion"
• Typical VOLP (output ground bounce) < 0.8V at Vcc = 3.3V, TA = 25°C
• ESD protection exceeds JESD 22

This product is suitable for memory address driving and all kinds of buffering applications where low power dissipation and high noise immunity are primary concerns. It is widely used in computer motherboards, servers, networking and telecommunication equipment, and embedded systems.

The 74LVT244APW,118 is also characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions. It is compliant with JEDEC standard no. 7A requirements and is compatible with both TTL input and output voltage levels. The product is supplied in a 20-pin TSSOP package, offering a reduced footprint compared to traditional DIP packages.

With its robust design and versatile features, the 74LVT244APW,118 from NXP is a preferred choice for designers looking for a reliable buffer/line driver solution that balances performance with power efficiency.
