SL74LS245 Overview
SL74LS245 Octal 3-State Noninverting Bus Transceiver These octal bus transceiver are designed for asynchronous twoway munication between data buses. The control function implementation minimized external timing requirements. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the directional control (DIR) input.
