The T/R input determines the direction of data Power-off high impedance inputs and outputs flow. The OE input disables both the A and B ports by plac- Supports Live Insertion and Withdrawal (Note 1) ing them in a high impedance state. t The 74VCX245 is designed for low voltage (1.4V to 3.6V) PD V applications with I/O compatibility up to 3.6V. CC 3.5 ns max for 3.0V to 3.6V V CC The 74VCX245 is fabricated with an advanced CMOS Static Drive (I /I ) OH OL technology to achieve high-speed operation while main- r24 mA 3.0V V CC taining low CMOS power dissipation. Uses proprietary noise/EMI reduction circuitry Latchup performance exceeds 300 mA ESD performance: Human body model 2000V Machine model 200V Leadless DQFN Pb-Free package Note 1: To ensure the high impedance state during power up and power down, OE should be tied to V through a pull up resistor. The minimum n CC value of the resistor is determined by the current sourcing capability of the driver.
