MC74LCX540DWR2G Description

Short technical summary and product information.

The ON Semiconductor MC74LCX540DWR2G is a high-performance, inverting octal buffer with a flow-through pinout. It operates from a 2.3V to 3.6V supply, making it suitable for low-voltage systems. This device features 5V tolerant inputs and outputs, allowing for interface capability with 5V TTL logic. The high impedance TTL compatible inputs reduce current loading on input drivers, while the TTL compatible outputs provide improved switching noise performance.

 

The MC74LCX540 is designed for applications such as memory address driving and TTL level bus-oriented transceiver applications. It offers a balanced output sink and source capability of 24mA. The device supports live insertion and withdrawal, and its IOFF specification guarantees high impedance when VCC is 0V. ESD protection is robust, with Human Body Model exceeding 2000V and Machine Model exceeding 200V.

 

This buffer is supplied in a 20-SOIC package with surface mount mounting type. It operates within an ambient temperature range of -40°C to 85°C. The device is Pb-free and halogen-free, complying with RoHS standards.
