Asynchronous Control Line. When LOAD = V
CC
, all the
400
internal active loads are on. When LOAD = GND,
external 400
loads must be used. The buffers
must
have a resistive load to maintain stability.

Digital Ground. 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 LATCH. If this con-
trol line is low, the 2nd-rank registers are transparent
when LATCH is low, passing data directly from the
1st-rank registers to the decoders.

In serial mode, WR (write) shifts data into the input regis-
ter. In parallel mode, WR loads data into the 1st-rank
registers. Data is latched on the rising edge.

If EDGE/
LEVEL
= V
CC
, data is loaded from the 1st-
rank registers to the 2nd-rank registers on the rising
edge of LATCH. If EDGE/
LEVEL
= GND, data is
loaded while LATCH = GND. In addition, data is
loaded during the execution of parallel-mode func-
tions 1011 through 1110, or if LATCH = V
CC
during
the execution of the parallel-mode “software-latch”
command (1111).
