STMicroelectronics M74HC240B1R Integrated Circuit

The M74HC240B1R is a high-speed CMOS octal bus buffer manufactured by STMicroelectronics, designed to provide a low-power, high-performance solution for a wide range of digital applications. This integrated circuit features eight non-inverting buffer/line drivers with 3-state outputs, making it ideal for driving bus lines or buffer memory address registers.

Constructed with silicon gate CMOS technology, the M74HC240B1R ensures that quiescent current is significantly reduced, offering an energy-efficient option for modern electronic devices. The device is capable of operating with a power supply range of 2V to 6V, providing compatibility with TTL levels while maintaining the speed and power consumption advantages of CMOS technology.

Each buffer/line driver of the M74HC240B1R has a separate input and output enable for greater flexibility, allowing the device to be used as a transceiver without the need for external inverters. The 3-state output configuration also means that multiple outputs can be connected to a common bus, which remains in a high-impedance state when not in use, thus preventing bus contention.

The M74HC240B1R is provided in a DIP-20 package, ensuring ease of integration into a variety of circuit boards and systems. Its robust design is characterized by high noise immunity and the ability to drive heavy load conditions, making it suitable for interfacing with high-capacity memory and other demanding digital circuits.
