To ensure the high impedance state during power up and power down, OEn 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. General Description The ALVC245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B ports by placing them in a high impedance state. The 74ALVC245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74ALVC245 is fabricated with an advanced CMOS technology to achieve high-speed operation while main- taining low CMOS power dissipation. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number. All packages are lead free per JEDEC: J-STD-020B standard.
