The SN54ACT16651 and 74ACT16651 are 16-bit bus transceivers that consist 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. These devices can be used as two 8-bit transceivers or one 16-bit transceiver.
Complementary output-enable (OEAB and ) inputs are provided to control the transceiver funcTIons. Select-control (SAB and SBA) inputs are provided to 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.
