DG2741, DG2742, DG2743 Vishay Siliconix Low-Voltage, 0.8 R , Dual SPST Analog Switch ON DESCRIPTION FEATURES The DG2741, DG2742, DG2743 are low voltage, single Low voltage operation (1.6 V to 3.6 V) supply, dual SPST analog switches. Designed for high Low on-resistance - R : 0.8 at 2.7 V DS(on) performance switching of analog signals, the DG2741, High current handling capacity: 150 mA continuous DG2742, DG2743 provide low on-resistance (0.8 at Off-isolation: - 56 dB at 1 MHz + 2.7 V), fast speed (t , t at 35 ns and 33 ns) and the ON OFF Fast switching: 25 ns t ability to handle signals over the entire analog voltage range. ON Low charge injection - Q : 5.8 pC INJ When operated on a + 3 V supply, control pins are Low power consumption: < 1 W compatible with 1.8 V digital logic. Additionally, on- ESD protection > 2 000 V resistance flatness and matching (0.18 and 0.08 , respectively) offer high accuracy between channels. BENEFITS High accuracy The DG2741 contains two normally open (NO) switches, the DG2742 contains two normally closed (NC) switches, and High bandwidth the DG2743 contains one normally open and one normally TTL and low voltage logic compatibility closed switch. Break-before-make is guaranteed. Low power consumption Reduced PCB space (SOT23-8 and MSOP-8) Built on Vishay Siliconixs low voltage submicron CMOS process, the DG2741, DG2742, DG2743 were designed to APPLICATIONS offer solutions that extend beyond audio/video functions, to providing the performance required for todays demanding Mixed signal routing mixed-signal switching in portable applications.
