The MAX14774 quad SPST and the MAX14779 dual SPDT Beyond-The-Rails switches support switching analog signals of up to ±25V using a single 3.0V to 5.5V supply. The MAX14774 is a quad SPST switch configuration with four EN_ control inputs, and the MAX14779 is a dual SPDT switch configuration with two EN_ and two S_ control inputs. Both the MAX14774 and MAX14779 have a flexible 1.62V to 5.5V CMOS logic interface.
The switches feature 2.5Ω (max) on-resistance and 18mΩ (typ) flatness at 85°C. The MAX14774 has a low on-leakage current of ±100nA (max) while the MAX14779 has ±200nA (max) at 85°C. The switches maintain the performance over the entire common-mode voltage range to maximum signal integrity. Each device can carry up to 200mA (max) of continuous current in either direction while operating from -40°C to +125°C.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The MAX1477X evaluation kit (EV kit) provides a proven design to evaluate the MAX14774, a quad single-pole/single-throw (SPST), or the MAX14779, a dual single-pole/double-throw (SPDT) Beyond-the-RailsTM analog switch. The MAX1477XEVKIT# is fully assembled and tested and comes populated with the MAX14774ATP+.
The MAX1477XEVKIT# can also be used to evaluate the MAX14779ATP+. See the Configure the MAX1477X EV Kit section for more information.
