description
The ’ABT18862 is a 20-bit transceiver designed
for asynchronous communication between data
buses. The control function implementation allows
for maximum flexibility in timing.
The ’ABT16862 can be used as two 10-bit
transceivers or one 20-bit transceiver. It allows
data transmission from the A bus to the B bus or
from the B bus to the A bus depending upon the
logic levels at the output-enable (OEAB and
OEBA) inputs.
To ensure the high-impedance state during power up or power down, 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 SN74ABT16862 is packaged in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT16862 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16862 is characterized for operation from –40
