16-Bit Bus Transceivers And Registers With 3-State Outputs

The 'ABT16646 devices consist 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
These devices CAN be used as two 8-bit transceivers or one 16-bit transceiver. Data on the A or B bus is clocked into the Registers on the low-to-high transition of the appropriate Clock (CLKAB or CLKBA) input. Figure 1 illustrates the four fundamental bus-management functions that CAN be performed with the 'ABT16646 devices.
Output-enable (OE) and direction-control (DIR) inputs are provided to control the transceiver functions. In the transceiver mode, data present at the high-impedance port may be stored in either Register or in both. The select-control (SAB and SBA) inputs CAN multiplex stored and real-time (transparent mode) 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. The direction control (DIR) determines which bus receives data when OE is low. In the isolation mode (OE high), A data CAN be stored in one Register and/or B data CAN be stored in the other Register
When an output function is disabled, the input function is still enabled and CAN be used to store and transmit data. Only one of the two buses, A or B, CAN be driven at a time.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT16646 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ABT16646 is characterized for operation from -40C to 85C.
