      INTERFACING - DIGITAL OUTPUTS AND CONTROLS
      (CONTD)
      DATA TRANSFERS
      Digital output data from the SD-14595/96/97 can be transferred
      to 8-bit and 16-bit bus systems. For 8-bit systems, the MSB and
      LSB bytes are transferred sequentially. For 16-bit systems all
      bits are transferred at the same time
      DATA TRANSFER TO 8-BIT BUS
      FIGURES 11 and 12 show the connections and timing for trans-
      ferring data from the SD-14595/96/97 to an 8-bit bus.
      As can be seen by the timing diagram, the following occurs:
      1. The converter INH control is applied and must remain low for
      a minimum of 500 ns before valid data is transferred.
      2. HBE is set to a low state (logic 0) 350 ns MIN after INH goes
      low and must remain low for a minimum of 150 ns before the
      MSB data (1-8) is valid and transferred.
      3. As HBE is set to a high state (logic 1), LBE is brought low for
      a 150 ns MIN before the LSB data is valid and transferred.
      4. LBE should go high (to logic 1) at least 100 ns MAX before
      another device uses the bus.
      5.Setting INH high when data transfer is done, the data refresh
      cycle can begin. Note the time it takes for INH to go to a logic 1
      should be 100 ns minimum before valid data is transferred.
      Note: For further understanding, refer to the beginning of this
      section (Digital Interface, Digital Angle Outputs, Digital Angle
      Output Timing, and Inhibit).
      16-BIT DATA TRANSFER
      Data transfer to the 16-bit bus is much simpler than the 8-bit bus.
      FIGURES 13 and 14 (page 8) show the connections and timing
      for transferring data from the SD-14595/96/97 to a 16-bit bus.
      As can be seen by the timing diagram the following occurs:
      1. The converter INH control is applied and must remain low for
      a minimum of 500 ns before valid data is transferred.
      2. HBE and LBE are set to a low state (logic 0) 350 ns MIN after
      INH goes low and must remain low for a minimum of 150 ns
      before the data (1-16) is valid and transferred.
      3. HBE and LBE should go high (to logic 1) at least 100 ns MAX
      before another device uses the bus.
      4. INH goes high and data transfer is done and the data refresh
      cycle can begin. Note the time it takes for INH to go to a logic 1
      should be 100 ns minimum before valid data is transferred.
      Note: For further understanding, refer to the beginning of this
      section (Digital Interface, Digital Angle Outputs, Digital Angle
      Output Timing, and Inhibit).
