description

The ´ABT16245 is a 16-bit (dual-octal) noninverting 3-statetransceiver designed for synchronous two-way communication betweendata buses. The control function implementation minimizes externaltiming requirements.

This device can be used as two 8-bit transceivers or one 16-bittransceiver. It allows data transmission from the A bus to the B busor from the B bus to the A bus depending upon the logic level at thedirection-control (DIR) input. The output-enable () input can be used to disable thedevice so that the buses are effectively isolated.

To ensure the high-impedance state during power up or powerdown,should be tiedto V_CC through a pullup resistor; the minimum value of theresistor is determined by the current-sinking capability of thedriver.

The SN74ABT16245 is available in TI's shrink small-outline package(DL), which provides twice the I/O pin count and functionality ofstandard small-outline packages in the same printed-circuit-boardarea.

The SN54ABT16245 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ABT16245 is characterized for operation from -40°C to85°C.
