74ALVCH2245 Low Voltage Bidirectional Transceiver with Bushold and 26 Series Resistors in B Outputs
General Description
The ALVCH2245 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 ALVCH2245 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 74ALVCH2245 is designed for low voltage (1.65V to 3.6V) VCC applications. The ALVCH2245 is also designed with 26 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 74ALVCH2245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.
