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.
