Serial Controlled, 8-Channel SPST Switch
The MAX335 analog switch with serial digital interface
offers eight separately controlled single-pole-singlethrow (SPST) switches. All switches conduct equally in
either direction, and on-resistance (100Ω) is constant
over the analog signal range.
These CMOS switches can operate continuously with
power supplies ranging from ±4.5V to ±20V and handle
rail-to-rail analog signals. Upon power-up, all switches are
off, and the internal serial and parallel shift registers are
reset to zero. The MAX335 is equivalent to two DG211
quad switches but controlled by a serial interface.
The interface is compatible with the Motorola SPI interface standard. Functioning as a shift register, this serial
interface allows data (at DIN) to be locked in synchronous with the rising edge of clock (SCLK). The shift register's output (DOUT) enables several MAX335s to be
daisy chained.

______________Detailed Description
Serial Digital Interface
Basic Operation
Refer to Figure 2. The MAX335 interface can be
thought of as an 8-bit shift register controlled by CS.
While CS is low, input data appearing at DIN is clocked
into the shift register synchronous with SCLK’s rising
edge. The data is an 8-bit word, each bit controlling
one of eight switches in the MAX335 (Table 1). DOUT is
the output of the shift register, with data appearing synchronous with SCLK’s falling edge. Data at DOUT is
simply the input data delayed by eight clock cycles.
When shifting the input data, D7 is the first bit in and
out of the shift register. While shifting data, the switches
remain in their original configuration. When the 8 bits of
data have been shifted in, CS is brought high. This
6
updates the new switch configuration and inhibits further data from entering the shift register. Transitions at
DIN and SCLK have no effect when CS is high, and
DOUT holds the last bit in the shift register.
The MAX335 three-wire serial interface is compatible
with the SPI™ and Microwire™ standards. If interfacing
with a Motorola processor serial interface, set CPOL = 0.
The MAX335 is considered a slave device (Figures 2
and 3). Upon power-up, the shift register contains all
zeros, and all switches are off.
The latch that drives the analog switch is only
updated on the rising edge of CS when SCLK is low.
If SCLK is high when CS rises, the latch will not be
updated until SCLK goes low. The CPOL = 1, CPHA = 1
SPI configuration does not update the latch correctly.
Daisy Chaining
For a simple interface using several MAX335s, “daisy
chain” the shift registers as shown in Figure 5. The CS
pins of all devices are connected together, and a
stream of data is shifted through the MAX335s in
series. When CS is brought high, all switches are
updated simultaneously. Additional shift registers may
be included anywhere in series with the MAX335 data
chain.
Addressable Serial Interface
When several serial devices are configured as slaves,
addressable by the processor, DIN pins of each
MAX335 are connected together (Figure 6). Address
decode logic individually controls CS of each slave
device. When a slave is selected, its CS is brought low,
data is shifted in, and CS is brought high to latch the
data. Typically, only one slave is addressed at a time.
DOUT is not used.
Digital Feedthrough
Digital feedthrough energy measures 100nV-sec, which
means that with no filtering at the signal channel,
feedthrough from a sharply rising clock edge into an
unfiltered switch channel can be measured at 1Vp-p for
100ns. However, even 100pF capacitance in the switch
channel, when combined with the switch resistance,
yields a filter that reduces this transient to 10mVp-p
typical. To reduce digital feedthrough, hysteresis
(150mV typ) was added to the SCLK input so triangle
or sine waves may be used.

__________Applications Information
8 x 1 Multiplexer
To use the MAX335 as an 8 x 1 multiplexer, tie all
drains together (COM0 to COM7); the mux inputs now
source each switch (NO0 to NO7). Input a single 0V to
+3V pulse at DIN. As this is clocked through the register by SCLK, each switch will sequence on one at a
time.
4-2 Differential Multiplexer
To use the MAX335 as a 4-2 differential multiplexer, tie
COM0 through COM3 together and COM4 through
COM7 together. Differential inputs will be the source
inputs as follows: (NO0, NO4), (NO1, NO5), (NO2,
NO6), (NO3, NO7). Figure 7 shows the serial input control at DIN required to turn on two switches making a
differential multiplexer.
D4
Reset Function
Pulsing VL below +0.8V initiates the power-up reset
function. The switches are set to the off position, and
the serial shift register is reset to all zeros.
Power-Supply Operation
The MAX335 operates with V = ±4.5V to ±20V and
VL = +5V. With V- tied to ground, the part operates with
V+ = +10V to +30V.
The VL supply sets TTL input compatibility at a 1.6V
switching threshold. As V L is raised, the switching
threshold is raised, so the part is no longer TTL compatible. The MAX335 also operates with a single power
supply: VL = V+ and V- = 0V. With VL tied to V+, the VL
supply cannot be used as a reset function.

CS is held low for four clock pulses; the first pulse is
clocked into the fifth switch position as the second
pulse is clocked into the first switch position. CS is
pulled high to update switches; then CS is pulled low,
and SCLK advances pulses to S1 and S5 positions,
where CS is pulled high to update, etc.

Tie COM0 to NO1 so that NO0 and COM1 are now

common output. Up to four SPDT switches can be
made from each MAX335. Multiples of four or more can
be made by daisy chaining devices. In Figure 8, DIN is
a pulse train. Again, CS is held low to clock in pulses
and CS is pulled high to update; CS is held low to shift
pulses, then pulled high to update, etc.
