IN74LS245 Overview
TECHNICAL DATA IN74LS245 Octal 3-State Noninverting Bus Transceiver These octal bus transceiver are designed for asynchronous two-way 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.
