DESCRIPTION/ORDERING INFORMATION

This 16-bit bus transceiver and register is designed

for 1.65-V to 3.6-V VCC operation.

The SN74LVCH16646A 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.
