description/ordering information

VCC VCC The ’ABT162245 devices are 16-bit noninverting 2B5 2A5 3-state transceivers designed for synchronous 2B6 2A6 two-way communication between data buses. GND GND The control-function implementation minimizes 2B7 2A7 external timing requirements. 2B8 2A8 2DIR 2OE

These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses effectively are isolated. The A-port outputs, which are designed to source or sink up to 12 m A, include equivalent 25-Ω series resistors to reduce overshoot and undershoot. These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
