The document introduces the 74LCX240 model product launched by Fairchild Semiconductor Corporation in 1994. The product is a low voltage octal buffer/line driver with 5V tolerant inputs and outputs. Its features include: 5V tolerant inputs and outputs, VCC specifications of 2.3V-3.6V, maximum 6.5ns propagation delay, maximum 10µA operating current, support for live insertion/withdrawal, ±24mA output drive, latch-up performance exceeding 500mA, and ESD performance exceeding 2000V.
The 74LCX240 is an inverting octal buffer and line driver designed for low voltage applications (2.3V to 3.6V) while interfacing with a 5V signal environment. It features proprietary noise/EMI reduction circuitry, supports live insertion and withdrawal, and offers high-speed operation with maximum propagation delays of 6.5ns at Vcc = 3.3V.
