SN54ALS243A
- Two-Way Asynchronous Communication Between Data Buses
- pnp Inputs Reduce dc Loading
- Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs
These quadruple bus transceivers are designed for asynchronous
two-way communication between data buses. The control-function
implementation allows for maximum flexibility in timing. These
devices allow data transmission from the A bus to the B bus or from
the B bus to the A bus depending upon the logic levels at the
output-enable (OEBA and
)
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 quadruple bus transceivers
the capability to store data by simultaneously enabling OEBA and
. Each output reinforces its input
in this transceiver configuration. When both control inputs are
enabled and all other data sources to the two sets of bus lines are
at high impedance, both sets of bus lines (eight in all) retain their
states. The 4-bit codes appearing on the two sets of buses are
identical.
The SN54ALS243A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS243A is characterized for operation from 0°C to 70°C.
