description
The ’ABTH25245 are 25- octal bus transceivers
designed
for
asynchronous
between data buses. They improve both the
performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
transceivers.
These
devices
allow
noninverted
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)
output-enable (OE) input can disable the device
so that both buses are effectively isolated. When
OE is low, the device is active.
These transceivers are capable of sinking 188 mA of I
lines on the incident wave. The distributed V
operation.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
