16-BIT BUS TRANSCEIVERS

WITH 3-STATE OUTPUTS

SCBS300F – MARCH 1994 – REVISED JULY 2005

DESCRIPTION

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
However, to ensure the high-impendance state above 2.1 V, OE should be tied to V
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.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
