The 'ABT16245A devices are 16-bit 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 transceviers 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 V

is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.

However, to ensure the high-impendance state above 2.1 V, OE should be tied to V

through a pullup resistor;

the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT16245A is characterized for operation over the full military temperature range of –55 ° C to 125 ° C.

The SN74ABT16245A is characterized for operation from –40 ° C to 85 ° C.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
