The ’ABTE16245 devices are 16-bit (dual-octal) noninverTIng 3-state transceivers designed for synchronous two-way 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. 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 are effectively isolated. When (OE) is low, the device is active.
The B port has an equivalent 25- series output resistor to reduce ringing. Active bus-hold inputs also are on the B port to hold unused or floating inputs at a valid logic level.
