These octal bus transceivers are designed for asynchronous communication between data buses. The implementation of control functions provides maximum timing flexibility.

These devices allow data transfer from bus A to bus B or from bus B to bus A based on the logic levels at the output enable (OEAB and OEBA) inputs.

The output enable inputs can be used to disable the device, effectively isolating the buses. The dual-enable configuration gives the transceiver the ability to latch data by enabling OEAB and OEBA simultaneously. In this configuration, each output reinforces its input. When both OEAB and OEBA are enabled and all other data sources on both sets of bus lines are in a high-impedance state, all 16 bus lines will retain their last state.

The SN54F621 operates over a temperature range of -55°C to 125°C. The SN74F621 operates over a temperature range of 0°C to 70°C.
