description
These octal bus transceivers provide for
asynchronous communication between data
buses. The control-function implementation
allows for maximum flexibility in timing. The
’ABT620 devices provide inverted data at the
outputs.
These devices allow data transmission from the
A bus to the B bus or from the B bus to the A bus,
depending on 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 total) 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 SN54ABT620 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74ABT620 is characterized for operation from –40
°
C to 85
