Description

The 74VCXH2245 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 VCXH2245 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 74VCXH2245 is designed for low voltage (1.65V to3.6V) VCC applications. The VCXH2245 is also designed
with 26W series resistance in the B Port outputs. Thisdesign reduces line noise in applications such as memory
address drivers, clock drivers, and bus transceivers transmitters
The 74VCXH2245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining
low CMOS power dissipation.
