The data flow verting 4-bit bidirectional bus driver. control is performed by placing one of a pair of buffers in When the terminal CS Is high-level, all outputs are in high-impedance state and allowing the other to transfer the high-impedance state, and when low-level, the direction of data. the bidirectional bus can be controlled by the terminal DIEN.
