DESCRIPTION/ORDERING INFORMATION
This 16-bit bus transceiver and register is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC16646A can be used as two 8-bit transceivers or one 16-bit transceiver. The device consists of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers.
