SN74ABT16245ADGVR

The ABT16245A is a 16-bit noninverting 3-state transceiver designed for synchronous bidirectional communication between data buses. The control function implementation minimizes external timing requirements. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. Depending on the logic level of the direction control (DIR) input, data can be transmitted from the A bus to the B bus, or from the B bus to the A bus. The device can be disabled via the output enable (OE) input to effectively isolate the buses. When VCC is between 0 V and 2.1 V, the device is in a high-impedance state during power-up or power-down. To ensure the high-impedance state is maintained when the voltage exceeds 2.1 V, OE should be connected to VCC through a pull-up resistor; the minimum resistance value is determined by the sink current capability of the driver.
