______________________________________________________________Pin Description
Note 1: Buffer inputs are internally grounded with a 1000 or 1001 command from the D3-D0 lines. AGND must be at 0.0V since the
gain setting resistors of the buffers are internally tied to AGND.

LOAD
Asynchronous control line. When LOAD = 1, all the 400
internal active
loads are on. When LOAD = 0, external 400
loads must be used. The
buffers MUST have a resistive load to maintain stability.

DGND
Digital Ground Pins. Both DGND pins must have the same potential and
be bypassed to AGND. DGND should be within ±0.3V of AGND.

When this control line is high, the 2nd-rank registers are loaded with the
rising edge of the LATCH line. If this control line is low, the 2nd-rank reg-
isters are transparant when LATCH is low, passing data directly from the
1st-rank registers to the decoders.

All V+ pins must be tied to each other and bypassed to AGND
separately (Figure 2).

execution of the parallel-mode "software-LATCH" command (1111).
