MAX395
Serially Controlled, Low-Voltage,
8-Channel SPST Switch

______________________________________________________________________________________
SCLK, each switch sequences one differential channel
at a time, starting with channel 7/0. After the first eight
bits have been sent, subsequent channel sequencing
can occur by repeating this sequence or, even faster,
by sending only one DIN high pulse and one CS low
pulse for each four clock pulses.
SPDT Switches
To use the MAX395 as a quad, single-pole/double-
throw (SPDT) switch, connect COM0 to NO1, COM2 to
NO3, COM4 to NO5, and COM6 to NO7, forming the
four “common” pins. Program these four switches with
pairs of instructions, as shown in Table 2.
Reset Function
RESET is the internal reset pin. It is usually connected
to a logic signal or V+. Drive RESET low to open all
switches and set the contents of the internal shift regis-
ter to zero simultaneously. When RESET is high, the
part functions normally and DOUT is sourced from V+.
RESET must not be driven beyond V+ or GND.
Power-Supply Considerations
Overview
The MAX395 construction is typical of most CMOS ana-
log switches. It has three supply pins: V+, V-, and
GND. V+ and V- are used to drive the internal CMOS
switches and to set the limits of the analog voltage on
any switch. Reverse ESD-protection diodes are inter-
nally connected between each analog signal pin and
both V+ and V-. If any analog signal exceeds V+ or V-,
one of these diodes will conduct. During normal opera-
tion, these (and other) reverse-biased ESD diodes leak,
forming the only current drawn from V+ or V-.
Virtually all the analog leakage current is through the
ESD diodes. Although the ESD diodes on a given sig-
nal pin are identical, and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V+ or V- and the analog signal. This means their
leakages vary as the signal varies. The difference in the
two diode leakages to the V+ and V- pins constitutes
the analog signal-path leakage current. All analog leak-
