ON Semiconductor MC74HCT541ADTR2 Octal Buffer/Line Driver

The MC74HCT541ADTR2 from ON Semiconductor is a high-performance, octal buffer and line driver designed to interface with 8-bit multi-plexed address/data buses in bus-oriented systems. This integrated circuit is a part of the HCT (High-speed CMOS TTL-compatible) family, which combines the best features of high-speed CMOS and TTL logic types.

With its true non-inverting outputs, the MC74HCT541ADTR2 is ideal for driving bus lines or buffer memory address registers. This IC provides a high level of drive while maintaining a fast propagation delay and low input capacitance. It operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL logic levels while offering the benefits of CMOS technology, such as lower power consumption and increased noise immunity.

The device features eight buffers with 3-state outputs that can be placed in a high-impedance state, effectively disconnecting the output from the bus. This is particularly useful in applications where multiple devices are connected to the same bus, allowing for controlled data flow without the risk of bus contention.

Key specifications of the MC74HCT541ADTR2 include:

• Operating Temperature Range: -55°C to +125°C
• Output Drive Capability: 15 LSTTL Loads
• Typical tpd (Propagation Delay Time): 8ns
• Low Input Current: 1µA
• Low Quiescent Current: 80µA Maximum (per IC)

This device is packaged in a TSSOP-20 (Thin Shrink Small Outline Package), offering a space-saving solution for PCBs (Printed Circuit Boards) with limited real estate. The MC74HCT541ADTR2 is also characterized for operation from -55°C to +125°C, ensuring reliable performance across a wide range of environmental conditions.

Whether used in personal computers, data communication equipment, or control systems, the MC74HCT541ADTR2 is an excellent choice for designers looking for a robust and versatile octal buffer/line driver. Its compatibility with existing TTL logic levels and improved performance characteristics make it an essential component in modern digital circuit design.
