ON Semiconductor MC74HC240ANG Octal 3-State Inverting Buffer/Line Driver

The MC74HC240ANG is a high-performance integrated circuit produced by ON Semiconductor, renowned for its exceptional quality and reliability in electronic components. This device is part of the high-speed CMOS family and is designed to operate at similar speeds while retaining the low power consumption of standard CMOS integrated circuits. It features an octal 3-state inverting buffer/line driver configuration, making it a versatile choice for a variety of applications in digital systems.

The MC74HC240ANG has eight inverting buffers with three-state outputs, providing the ability to drive bus lines or buffer memory address registers. Its 3-state outputs allow for connection to a bus-oriented system without the need for external pull-up resistors, thus simplifying design and reducing component count. The device can drive up to 15 LSTTL loads, ensuring compatibility with a range of legacy systems and technologies.

With an operating voltage range of 2V to 6V, the MC74HC240ANG is suitable for interfacing with both standard 5V systems and newer, lower-voltage systems. This flexibility makes it an ideal choice for mixed-voltage applications, as well as for battery-powered devices where power efficiency is crucial. The input levels are also compatible with standard CMOS outputs, making this device easily integrable with other CMOS logic components.

The MC74HC240ANG is housed in a 20-lead PDIP (Plastic Dual-In-Line Package), providing a robust and easy-to-handle component for through-hole mounting. This package is widely used and preferred for prototyping and in applications where space is not a primary constraint.

Key features of the MC74HC240ANG include:

• Typical propagation delay: 8ns at VCC = 5V, CL = 15pF, TA = 25°C
• Low quiescent current: 80µA maximum (74HC)
• Output drive capability: 15 LSTTL loads
• 3-state outputs for bus interfacing
• Wide operating voltage range: 2V to 6V
• Compatible with TTL levels

Whether you are developing high-speed data processing systems, communication interfaces, or any digital application requiring reliable buffering and line driving capabilities, the MC74HC240ANG from ON Semiconductor is a solid choice that combines performance with practicality.
