The inputs tolerate voltages up to 7V allowing the interface of 5V systems to 3V systems. 2.3V-3.6V VCC specifications provided 6.0ns tPD max. (VCC = 3.3V), 10A ICC max. Power down high impedance inputs and outputs Supports live insertion/withdrawal(1) 24mA output drive (VCC = 3.0V) Implements proprietary noise/EMI reduction circuitry The 74LCX125 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Latch-up performance exceeds JEDEC 78 conditions ESD performance: - Human body model > 2000V - Machine model > 100V Leadless DQFN package Note: 1. To ensure the high-impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value of the resistor is determined by the current-sourcing capability of the driver.
