STMicroelectronics 74AC240MTR Octal Buffer/Line Driver

The 74AC240MTR is a high-performance, octal buffer and line driver designed to interface with 8-bit microprocessors and bus-oriented systems. Manufactured by STMicroelectronics, a leader in semiconductor solutions, this integrated circuit is part of the 74AC series known for its high speed and robust performance.

With its dual-in-line 20-lead SO package, the 74AC240MTR offers a compact solution for systems requiring high drive capability. The device features eight non-inverting buffers with 3-state outputs, ensuring efficient bus management in complex digital systems. Each buffer has a separate output-enable (OE) input, which allows the user to control the output states in a flexible manner.

The 74AC240MTR operates over a broad voltage range from 2V to 6V and is characterized for operation from -55°C to +125°C. This wide operating range makes it suitable for use in a variety of challenging environments and applications. The device's high noise immunity and low power consumption are critical features for battery-operated and portable devices, where power efficiency is paramount.

Key features of the 74AC240MTR include:

• High-speed operation: tPD = 4.5ns (max) at VCC = 5V
• Low power dissipation: ICC = 4µA (max) at TA = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Power-off disable outputs permit "live insertion"
• Supports live insertion and withdrawal (partial power-down)

Applications for the 74AC240MTR include memory drivers, bus-oriented systems, and buffer memory address registers. Its ability to drive heavy loads and provide high-speed data transmission makes it an excellent choice for telecommunications, computing, and industrial applications where reliable data handling is required.

STMicroelectronics ensures the 74AC240MTR meets stringent quality standards, providing designers with a reliable component for their high-speed digital logic circuits. With its advanced features and robust performance, the 74AC240MTR is a versatile choice for enhancing the efficiency and reliability of digital systems.
