ON Semiconductor MC74LCX541DTR2 Octal Buffer/Line Driver

The ON Semiconductor MC74LCX541DTR2 is a high-performance, octal buffer/line driver designed to interface with 3.3V and 5V systems. This integrated circuit is a part of the LCX family, which is known for its low voltage operation and low power consumption. The device comes in a TSSOP-20 package, making it compact and suitable for space-constrained applications.

With its bidirectional interface and non-inverting buffers, the MC74LCX541DTR2 provides a versatile solution for driving bus lines or buffering memory address registers. It 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 creating bidirectional bus-oriented systems.

The MC74LCX541DTR2 operates over a broad voltage range (from 2.3V to 3.6V) and provides 5V tolerant inputs, which allows for mixed-voltage system integration. The device is characterized for operation from -40°C to +85°C, ensuring reliability over a wide range of environmental conditions.

One of the key attributes of the MC74LCX541DTR2 is its ability to support live insertion and withdrawal (hot swapping) without causing glitches on the power supply or bus lines. This feature is crucial for systems that require maintenance or upgrades without power-down periods, such as servers and telecommunications equipment.

For protection, the device includes built-in hysteresis, which helps to prevent noise from triggering unintended state changes. Additionally, the MC74LCX541DTR2 is equipped with over-voltage tolerant inputs and outputs to protect against static discharge and transient excess voltage, ensuring the longevity and durability of the product.

Overall, the MC74LCX541DTR2 from ON Semiconductor is a robust and versatile component that addresses the needs of modern digital systems requiring reliable high-speed data transmission and interfacing. Its features make it an excellent choice for a wide range of applications, including computing, networking, and industrial systems.
