ON Semiconductor MC74HC541AN Octal Buffer/Line Driver

The MC74HC541AN is a high-performance octal buffer and line driver designed to interface with 8-bit microprocessors and bus-oriented systems. Manufactured by ON Semiconductor, a leader in semiconductor solutions, this integrated circuit is part of the HC family and is fabricated with silicon gate CMOS technology. It boasts a robust set of features that make it ideal for a wide array of digital applications.

This IC provides eight high-speed non-inverting buffers with 3-state outputs. The 3-state outputs allow for connection to a bus-structured system and are capable of driving up to 15 LSTTL loads. Due to its high noise immunity characteristic of CMOS technology and its significant output drive capability, the MC74HC541AN is suitable for interfacing with high-speed logic systems and can easily drive capacitive loads.

The device is equipped with two active-low output enable inputs (\( \overline{OE1} \) and \( \overline{OE2} \)), which, when high, force the outputs into a high impedance state. This feature is particularly useful for multiplexing applications and prevents bus contention in a shared bus environment. The inputs are compatible with standard CMOS outputs, with threshold voltage levels that allow for TTL compatibility when powered by a 5V supply.

ON Semiconductor's MC74HC541AN operates over a wide voltage range from 2V to 6V and offers low input current of 1µA (max) and low quiescent supply current of 80µA (max), which is a testament to its low-power consumption. The device is available in a standard 20-pin DIP (Dual In-line Package), making it easy to integrate into a variety of circuit boards.

With its robust design and ON Semiconductor's commitment to quality, the MC74HC541AN is a reliable choice for system designers looking to add a high-performance octal buffer/line driver to their digital applications. Its versatility and high-drive capability make it an essential component for bus-oriented systems requiring a high degree of control over data transmission and reception.
