They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT242 are quad bus transceivers featuring inverting 3-state bus compatible outputs in both send and receive directions. They are designed for 4-line asynchronous 2-way data communications between data buses. The output enable inputs (OEA and OEB) can be used to isolate the buses. The “242” is similar to the “243” but has inverting outputs.
