Fairchild Semiconductor 74VCX245
The 74VCX2245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The VCX2245 is also designed with 26Ω series resistance in the B Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers transmitters The 74VCX2245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.| Part No. | 74VCX245 |

GENERAL DESCRIPTION
The VCX2245 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.FEATURES
