54ACT16652 16-BIT TRANSCEIVERS/REGISTERS

The ’ACT16652 are 16-bit bus transceivers consisting 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 devices can be used as two 8-bit transceivers or one 16-bit transceiver. Complementary output-enable (OEAB and OEBA) inputs are provided to control.

Features

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. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the ’ACT16652. 54ACT16652, 74ACT16652 16-BIT TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS SCAS128C
