NEXPERIA 74HCT541D Octal Buffer/Line Driver, SOIC-20

The NEXPERIA 74HCT541D is an octal (8-bit) non-inverting buffer and line driver featuring 3-state outputs, designed for robust signal management in digital circuits. It operates from a 4.5V to 5.5V supply, making it ideal for 5V TTL-level systems. A key feature is the inclusion of two independent output enable pins (OE1 and OE2), providing flexible control over the output states; a high logic level on either enable pin forces all outputs into a high-impedance OFF-state, facilitating bus-oriented applications.

The inputs are equipped with clamp diodes, allowing designers to use current-limiting resistors for interfacing with signals that exceed the VCC supply voltage, thereby offering enhanced protection and design flexibility. The device boasts very low input leakage current (±1μA) and off-state output current (±10μA), contributing to minimal power consumption and improved system efficiency.

Manufactured to meet JEDEC standard number 7A, this integrated circuit is built for reliability and consistent performance. Its specifications, including a wide operating temperature range from -40°C to 125°C, make it suitable for demanding industrial environments where component durability is critical.
