Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation.
Note 2: I_O Absolute Maximum Rating must be observed, limited to 4.6V.
Note 3: Floating or unused control inputs must be held HIGH or


Description

The 74ALVCH245WM 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 of the 74ALVCH245WM disables both the A and B Ports by placing them in a high impedance state. The ALVCH245 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.

The 74ALVCH245WM is designed for low voltage (1.65V to 3.6V) V_CC applications.

The 74ALVCH245WM is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.
