Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V or lower power supply systems. The sub-micron CMOS technology used SOT23-5L SOT323-5L Flip-Chip5 (Max dim = 1.3x1.3mm) ORDER CODES PACKAGE T&R SOT23-5L SOT323-5L Flip-Chip5 74LX1G125STR 74LX1G125CTR 74LX1G125BJR allow ultra low power consumption and guarantee optimized operations between 2.8V and 1.8V system, as Smart Phone, Digital Still Camera, PDA, Notebook, or each other battery powered equipment. All inputs and outputs are equipped with protection circuits against ESD discharge.
