74ALVCH2245 - Low Voltage Bidirectional Transceiver

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.

74ALVCH2245 Low Voltage Bidirectional Transceiver with Bushold January 2002 Revised January 2002 74ALVCH2245 Low Voltage Bidirectional Transceiver with Bushold and 26Ω 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.
