Texas Instruments 74ACT16651

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. view all in datasheet
