General Description

The LCX16646 contains sixteen 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 16-bit operation.The DIR inputs determine the direction of data flow through the device.

The CPAB and CPBA inputs load data into the registers on the LOW-to-HIGH transition (see Functional Description).
