LCX family is optimized for on-board buffering applications and provides mixed 2.5V/3.3V-5V capability by providing 5V over voltage tolerance on both the inputs and outputs. This family of popular gates, MSI, octal and 16-bit functions has maximum propa- gation delays similar to FAST and FACT. LCX also offers low CMOS power, low noise, and balanced output high-drive (±24 mA).
The Fairchild Semiconductor LCX Family is a line of popular logic devices designed specifically for on-board buffering applications. This family offers mixed voltage capability (2.5V/3.3V—5V) by providing 5V overvoltage tolerance on both inputs and outputs, allowing interfaces to 5V and/or 3V devices.
The LCX family supports an extended supply voltage operation from 2.0V to 3.6V.
The maximum propagation delay for the LCX244 is 6.5 ns.
The maximum propagation delay for the LCX16244 is 4.5 ns.
