The 74ALS244AN, manufactured by NXP Semiconductors, is a high-performance octal buffer and line driver designed to interface with 8-bit microprocessors and bus-oriented systems. This integrated circuit is part of the Advanced Low-Power Schottky (ALS) family, which is known for its combination of high speed and low power consumption.

Key Features:

• Logic Type: Octal Buffer/Line Driver with 3-state outputs
• Bus Hold: No bus hold feature, ensuring minimal cross-talk and signal integrity on the bus lines
• Supply Voltage: Typically 5V, with a range of 4.5V to 5.5V, making it suitable for TTL level systems
• Output Current: Capable of driving -15 mA at the high level and 24 mA at the low level, allowing for direct interfacing with bus lines
• Propagation Delay: Fast propagation delay times, with t<sub>PLH and t<sub>PHL typically at 6 ns, ensuring quick response times for critical applications
• Operating Temperature: Designed to operate over a wide temperature range from 0°C to 70°C
• Package: Housed in a 20-pin DIP (Dual In-line Package), suitable for through-hole mounting
