The MAX395 8-channel, serially controlled, single-pole/sin-
gle-throw (SPST) analog switch offers eight separately
controlled switches. The switches conduct equally well in
either direction. On-resistance (100Ω max) is matched
between switches to 5Ω max and is flat (10Ω max) over
the specified signal range.
These CMOS devices can operate continuously with
dual power supplies ranging from ±2.7V to ±8V or a
single supply between +2.7V and +16V. Each switch
can handle rail-to-rail analog signals. The off leakage
current is only 0.1nA at +25°C or 5nA at +85°C.
Upon power-up, all switches are off, and the internal shift
registers are reset to zero. The MAX395 is electrically
equivalent to two MAX391 quad switches controlled by a
serial interface, and is pin compatible with the MAX335.
The serial interface is compatible with SPI™/QSPI™ and
Microwire™. Functioning as a shift register, it allows data
(at DIN) to be clocked in synchronously with the rising
edge of clock (SCLK). The shift register’s output (DOUT)
enables several MAX395s to be daisy chained.
All digital inputs have 0.8V to 2.4V logic thresholds, ensur-
ing both TTL- and CMOS-logic compatibility when using
±5V supplies or a single +5V supply.
