description
The
′
ABT620A bus transceiver is designed for
asynchronous communication between data
buses. The control function implementation allows
for maximum flexibility in timing. The
′
ABT620A
provides inverted data at its outputs.
These devices allow 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.
The output-enable inputs can be used to disable the device so that the buses are effectively isolated. The
dual-enable configuration gives the transceivers the capability of storing data by simultaneously enabling OEAB
and OEBA. When both OEAB and OEBA are enabled and all other data sources to the two sets of bus lines are
at high impedance, both sets of bus lines (16 in all) will remain at their last states. In this way, each output
reinforces its input in this configuration.
To ensure the high-impedance state during power up or power down, OEBA 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.
OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by
the current-sourcing capability of the driver.
The SN74ABT620A is packaged in TI’s shrink small-outline package (DB), which provides the same I/O pin
count and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54ABT620A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT620A is characterized for operation from –40
°
C to 85
°
C.
