FAST AND LS TTL DATA
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.
