The MC74LCX244 is a high-performance, non-inverting octal buffer from ON Semiconductor, operating from a 1.65V to 5.5V supply. This device is suitable for memory address driving and TTL level bus-oriented transceiver applications.
Key electrical characteristics include a wide supply voltage range of 1.65V to 5.5V, with 5V tolerant inputs and outputs, allowing interface capability with 5V TTL logic. The buffer provides a balanced output sink and source capability of 24mA. It also features near-zero static supply current in all three logic states, which substantially reduces system power requirements.
The MC74LCX244 is available in a 20-QFN (2.5x4.5) exposed pad package, designed for surface mount applications. It operates across a wide temperature range of -55°C to 125°C (TA).
This buffer supports live insertion and withdrawal, and its IOFF specification guarantees high impedance when VCC is 0V. Latchup performance exceeds 500mA, and ESD protection is rated at over 2000V for the Human Body Model.
