Vishay Siliconix
Latchable Single 8-Ch/Differential 4-Ch Analog Multiplexers
DESCRIPTION
FEATURES
The DG528 is an 8-channel single-ended analog multiplexer
• Low RDS(on): 270 
designed to connect one of eight inputs to a common output
• 44 V Power Supply Rating
as determined by a 3-bit binary address (A0, A1, A2). DG529,
• On-Board Address Latches
a 4-channel dual analog multiplexer, is designed to connect
• Break-Before-Make
one of four differential inputs to a common differential output
• Low Leakage - ID(on): 30 pA
as determined by its 2-bit binary address (A0, A1) logic.
BENEFITS
These analog multiplexers have on-chip address and control
• Improved System Accuracy
latches to simplify design in microprocessor based applica-
• Microporcessor Bus Compatible
tions. Break-before-make switching action protects against
• Easily Interfaced
momentary shorting of the input signals. The DG528/529 are
• Reduced Crosstalk
built on the improved PLUS-40 CMOS process. A buried

layer prevents latchup.
• Data Acquisition Systems
The on chip TTL-compatible address latches simplify digital
• Automatic Test Equipment
interface design and reduce board space in data acquisition
• Avionics and Military Systems
systems, process controls, avionics, and ATE.

DETAILED DESCRIPTION
The internal structure of the DG528/DG529 includes a 5-V
logic interface with input protection circuitry followed by a
latch, level shifter, decoder and finally the switch constructed
with parallel n- and p-channel MOSFETs (see Figure 1).
The logic interface circuit compares the TTL input signal
against a TTL threshold reference voltage. The output of the
comparator feeds the data input of a D type latch. The level
sensitive D latch continuously places the DX input signal on
the QX output when the WR input is low, resulting in transparent latch operation. As soon as WR returns high, the latches
hold the data last present on the DX input, subject to the minimum input timing requirements.
Following the latches the QX signals are level shifted and
decoded to provide proper drive levels for the CMOS
switches. This level shifting insures full on/off switch operation
for any analog signal present between the V+ and V- supply
rails.
The EN pin is used to enable the address latches during the
WR pulse. It can be hard-wired to the logic supply or to V+ if
one of the channels will always be used (except during a reset)
or it can be tied to address decoding circuitry for memory
mapped operation. The RS pin is used as a master reset. All
latches are cleared regardless of the state of any other latch
or control line. The WR pin is used to transfer the state of the
address control lines to their latches, except during a reset or
when EN is low (see Truth Tables).

Notes:
a. Application Hints are for DESIGN AID ONLY, not guaranteed and not subject to production testing.
b. Electrical Parameter Chart based on V+ = 15 V, V- = - 15 V, VR = GND.
c. Operation below ± 8 V is not recommended.
The DG528/DG529 minimize the amount of interface hardware between a microprocessor system bus and the analog
system being controlled or measured. The internal TTL compatible latches give these multiplexers write-only memory, that
is, they can be programmed to stay in a particular switch state
(e.g., switch 1 on) until the microprocessor determines it is
necessary to turn different switches on or turn all switches off
(see Figure 9).
The input latches become transparent when WR is held low;
therefore, these multiplexers operate by direct command of
the coded switch state on A2, A1, A0. In this mode the DG528
is identical to the popular DG508A. The same is true of the
DG529 versus the popular DG509A.
During system power-up, RS would be low, maintaining all
eight switches in the off state. After RS returned high the
DG528 maintains all switches in the off state. When the system program performs a write operation to the address assigned to the DG528, the address decoder provides a CS
active low signal which is gated with the WRITE (WR) control
signal. At this time the data on the DATA BUS (that will determine which switch to close) is stabilizing. When the WR signal
returns to the high state, (positive edge) the input latches of
the DG528 save the data from the DATA BUS. The coded information in the A0, A1, A2 and EN latches is decoded and the
appropriate switch is turned on.
The EN latch allows all switches to be turned off under program control. This becomes useful when two or more DG528s
are cascaded to build 16-line and larger multiplexers.
