description

These octal 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 (OEAB and OEBA) inputs.

The output-enable inputs disable the device so that the buses are effectively isolated. The dual-enable

configuration gives the transceivers the capability to store data by simultaneously enabling OEAB and OEBA.

Each output reinforces its input in this transceiver configuration. When both OEAB and OEBA are enabled and

all other data sources to the two sets of bus lines are in the high-impedance state, both sets of bus lines (16 total)

remain at their last states. The 8-bit codes appearing on the two sets of buses are identical for the

SN74ALS621A, SN74ALS623A, and SN74AS623 or complementary for the SN74ALS620A.

The -1 versions of the SN74ALS620A and SN74ALS621A are identical to the standard versions, except that

the recommended maximum IOL is increased to 48 mA in the -1 versions.

The SN74ALS620A, SN74ALS621A, SN74ALS623A, and SN74AS623 are characterized for operation from

0°C to 70°C.
