ON Semiconductor MC74HC240ADTR2G Octal 3-State Inverting Buffer/Line Driver

The MC74HC240ADTR2G is a high-performance integrated circuit manufactured by ON Semiconductor, designed to provide efficient and reliable buffering and driving capabilities for a wide range of digital applications. This octal 3-state inverting buffer/line driver belongs to the 74HC family, which is well-known for its high-speed CMOS technology.

Constructed with silicon gate CMOS technology, the MC74HC240ADTR2G ensures low power consumption while maintaining a high noise immunity characteristic of CMOS integrated circuits. Its robust design enables the device to operate over a broad voltage range of 2V to 6V, making it suitable for interfacing with both TTL and CMOS logic levels without the need for external components to adjust voltage levels.

The device features eight inverting buffers with 3-state outputs, which can be used independently or in combination to drive bus lines or buffer memory address registers. The 3-state outputs ensure that multiple devices can share a common bus without interference, as the outputs can be placed in a high-impedance state, effectively disconnecting them from the bus.

Each buffer has two inputs: an active-low Output Enable (OE) and a data input (D). When the OE input is low, the buffer is active, and the output is the inverse of the data input. When OE is high, the output is in the high-impedance state, allowing other devices to control the bus.

The MC74HC240ADTR2G comes in a TSSOP-20 package, which is compact and suitable for surface-mount technology (SMT), providing a space-saving solution for densely packed circuit boards. Its temperature range of -55°C to +125°C ensures reliable operation even in extreme environmental conditions.

Applications for this IC include driving bus lines in computing systems, buffering data lines in communication infrastructure, and providing additional drive capability for memory address registers in microprocessor systems. The versatility and performance of the MC74HC240ADTR2G make it an excellent choice for designers looking for a reliable buffer/line driver solution.

With its combination of advanced CMOS technology, wide operating voltage range, and 3-state output flexibility, the MC74HC240ADTR2G from ON Semiconductor is an essential component for modern electronic designs requiring high-speed, low-power, and reliable signal buffering and driving capabilities.
