1 / 20 page SN54BCT245, SN74BCT245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS013H – SEPTEMBER 1998 – REVISED MAY 2002 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers D ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) description These octal bus transceivers are designed for asynchronous communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated.
