SN54/74LS623

OCTAL BUS TRANSCEIVER

WITH 3-STATE OUTPUT

The SN54 / 74LS623 series is an octal bus transceiver designed for

asynchronous two-way communication between data buses. Control function

implementation allows maximum timing flexibility. Enable inputs may be used

to disable the device so that buses are effectively isolated. Depending on the

Logic Levels at the enable inputs, Data transmission is allowed from the A bus

to the B bus or from the B bus to the A bus. The dual-enable configuration

gives the LS623 the capability to store data by simultaneous enabling of GBA

and GAB. Each output reinforces its input in this transceiver configuration.

Thus, when both control inputs are enabled all other data sources to the two

sets of bus lines (16 in all) will remain at their last states.
