TI 5962-9559001QXA

The ABT16640 is an inverting 16-bit transceiver designed for asynchronous communication between data buses. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. Depending on the logic levels of the direction control (1DIR and 2DIR) inputs, it allows data transfer from bus A to bus B, or from bus B to bus A. The output enable (1OE and 2OE) inputs can be used to disable the device, effectively isolating the buses. To ensure a high-impedance state during power-up or power-down, OE should be connected to VCC through a pull-up resistor; the minimum resistor value is determined by the sink current capability of the driver. The SN54ABT16640 operates over a temperature range of -55℃ to 125℃. The SN74ABT16640 operates over a temperature range of -40℃ to 85℃.
