Table 2. Channel/Output Selection
When each serial word is complete, the value is stored
in the SRAM at the address indicated and the control
bits are saved. Note that data may be corrupted if CS is
not held low for an integer multiple of 24 bits.
All the digital inputs include Schmitt-trigger buffers to
accept slow-transition interfaces. Their switching thresh-
old is compatible with TTL and most CMOS logic levels.

Sample-and-Hold Outputs
The 24-bit serial-input format, shown in Figure 4, com-
prises 16 bits (D12–D0 and S3–S0 = 0), 5 address bits
(A4–A0), 2 control bits (C1, C0), and a fill zero. The
address code selects the output channel as shown in
Table 2. The control code configures the device as fol-
lows:
1) If C1 = 1, immediate-update mode is selected.
2) If C0 = 0, the internal sequencer clock is selected. If
If C1 = 0, burst mode is selected.
C0 = 1, the external sequencer clock is selected.
This must be repeated with each data word to main-
tain external input.
