The LCX32646 contains thirty-two non-inverting bidirectional registered bus transceivers with 3-STATE outputs, providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Each byte has separate control inputs which can be shorted together for full 32-bit operation.The DIRn inputs determine the direction of data flow through the device. The CPABn and CPBAn inputs load data into the registers on the LOW-toHIGH transition (see Functional Description).
