DESCRIPTION
The 'ABT16245A devices are 16-bit noninverting 3-state transceivers designed for synchronous two-way
communication

16-BIT BUS TRANSCEIVERS
WITH 3-STATE OUTPUTS
SCBS300F–MARCH 1994–REVISED JULY 2005
implementation
minimizes
external
timing
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
CC
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
CC
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.
