description
The
noninverting 3-state transceiver designed for
synchronous two-way communication between
data buses. The control function implementation
minimizes external timing requirements.
′
ABT16245
is
a
16-bit
(dual-octal)
This device can be used as two 8-bit transceivers
or one 16-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 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.
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 SN74ABT16245 is available 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 SN54ABT16245 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16245 is characterized for operation from –40
°
C to 85
°
C.
