SN54ABT16623 Datasheet | Texas Instruments

description The ’ABT16623 are 16-bit transceivers designed for asynchronous munication between data buses. The control-function implementation allows for maximum flexibility in timing. The ’ABT16623 provide true data at the outputs. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They 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. Each output reinforces its input in this configuration. 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 (32 total) remain at their last states.
