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-enableconfigurationgivesthetransceiversthecapabilityofstoringdatabysimultaneouslyenablingOEAB

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

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°C.
