This 16-bit bus transceiver and register is designed for 1.65-V to 3.6-V V_CC operation.

The SN74LVCH16652A consists of D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The device can be used as two 8-bit transceivers or one 16-bit transceiver.

Complementary output-enable (OEAB and OEBA\) inputs control the transceiver functions. Select-control (SAB and SBA) inputs select whether real-time or stored data is transferred. A low input level selects real-time data, and a high input level selects stored data. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data.
