ON Semiconductor MC74HCT240ADWR2 Octal 3-State Inverting Buffer/Line Driver

The ON Semiconductor MC74HCT240ADWR2 is a high-performance, octal 3-state inverting buffer/line driver designed to interface with 8-bit bus systems. This integrated circuit is from the HCT family, which means it is compatible with standard CMOS logic while providing the ability to interface with TTL logic levels. This makes the MC74HCT240ADWR2 a versatile choice for facilitating communication between different logic families within a system.

Constructed with silicon gate CMOS technology, it possesses the high noise immunity and low power consumption characteristic of CMOS integrated circuits, along with the ability to drive 15 LSTTL loads. The MC74HCT240ADWR2 features eight inverting buffers with three-state outputs, allowing for bidirectional operation or connection to a bus-oriented system. When the output-enable (OE) input is high, the outputs are in a high-impedance state, which effectively disconnects them from the bus, providing a 'floating' effect.

Available in a wide-body SOIC-20 package, the MC74HCT240ADWR2 ensures a compact footprint on PCBs, making it suitable for space-constrained applications. Its operating temperature range from -55°C to +125°C ensures reliability across various environmental conditions, making it an ideal choice for automotive, industrial, and consumer electronics applications where robust performance is required.
