8287 Octal Bus Transceiver – Datasheet

The M8287 is transceivers 8-bit transceivers with high impedance outputs. With T active HIGH and OE active LOW, data at the Ap-A7 pins is driven onto the Bo-B7 pins. With T inactive LOW and OE active LOW data at the Bo-B7 pins is driven onto the Ap-A7 pins. No output low glitching will occur whenever the transceivers are entering or leaving the high impedance state.
