_______________Detailed Description
The internal structures of the DG528/DG529 include
translators for the A2/A1/A0/EN/WR/RS digital inputs,
latches, and a decode section for channel selection
(Truth Tables). The gate structures consist of parallel
combinations of N and P MOSFETs.
WRITE (WR) and RESET (RS) strobes are provided for
interfacing with P-bus lines (Figure 9), alleviating the
need for the P to provide constant address inputs to
the mux to hold a particular channel.
When the WR strobe is in the low state (less than 0.8V)
and the RS strobe is in the high state (greater than
2.4V), the muxes are in the transparent mode—they act
similarly to nonlatching devices, such as the DG508A/
DG509A or the HI508/HI509.
When the WR goes high, the previous BCD address
input is latched and held in that state indefinitely. To
pull the mux out of this state, either WR must be taken
low to the transition state, or RS must be taken low to
turn off all channels.
RS turns off all channels when it is low, which resets
channel selection to the channel 1 mode.
The DG528/DG529 work with both single and dual sup-
plies and function over the +5V to +30V single-supply
range. For example, with a single +15V power supply,
analog signals in the 0V to +15V range can be
switched normally. If negative signals around 0V are
expected, a negative supply is needed. However, only
-5V is needed to normally switch signals in the -5V to
+15V range (-5V, +15V supplies). No current is drawn
from the negative supply, so Maxim’s MAX635 DC-DC
converter is an ideal choice.
The EN latch allows all switches to be turned off under
program control. This is useful when two or more
DG528s are cascaded to build 16-line and larger ana-
log-signal multiplexers.
