General Description
The MAX349/MAX350 are 8-channel and dual 4-channel
serially controlled multiplexers (muxes). These muxes
conduct equally well in either direction. On-resistance
(100
max) is matched between switches to 16 max
and is flat (10
max) over the specified signal range.
These CMOS devices can operate continuously with
dual power supplies ranging from ±2.7V to ±8V or a sin-
gle supply between +2.7V and +16V. Each mux 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 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 MAX349s or MAX350s
to be daisy chained.
All digital inputs have 0.8V or 2.4V logic thresholds,
ensuring both TTL and CMOS-logic compatibility when
using ±5V supplies or a single +5V supply.
