CONTROL B
The MAX14774/MAX14779 analog switches support
analog signals up to ±25V using a single 3.0V to 5.5V
supply. The MAX14774 has four independent analog
switches with separate control inputs, while the
MAX14779 has two SPDT analog switches. Both parts
support separate logic level inputs, allowing flexible
CMOS input levels from 1.62V to 5.5V.

The MAX14774/MAX14779 feature a 2.5Ω (max) on-
resistance and an 18mΩ (typ) flatness at +85°C. The
MAX14774 has a low ±100nA (max) on-leakage current
at +85°C, while the MAX14779 has ±200nA (max). Each
switch can carry up to ±200mA (max) of continuous
current in either direction. The switches maintain the
performance over the entire common-mode voltage
range. Both parts are specified for -40°C to +125°C
industrial temperature range and are available in a 20
pin (4mm x 4mm) TQFN package.
