7 / 11 page Detailed Description The MAX4699/MAX4701 are low-voltage CMOS analog switches that operate from a single +1.8V to +5.5V power supply. The MAX4702 requires an additional logic supply that allows for setting lower logic thresh- olds. The MAX4699/MAX4701 are double-pole/double- throw (DPDT) devices. The MAX4702 is a quad single-pole/double-throw (SPDT) device. These devices feature a break-before-make switching, fast switching speeds (with V+ = 5V: tON = 18ns max, tOFF = 9ns max and with V+ = 3V: tON = 35ns, tOFF = 20) and rail-to-rail signal handling. A logic input on the MAX4702 allows for logic thresholds as low as 1.0V. Applications Information Analog Signal Levels Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in on- resistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO, NC, and COM pins can be used as either inputs or outputs. _______________________________________________________________________________________ 7 Low-Voltage, Dual DPDT/Quad SPDT Analog Switches in QFN Pin Description TQFN-EP PIN TSSOP PIN MAX4699/ MAX4701 MAX4702 MAX4701 MAX4702 NAME FUNCTION 1 1 3 3 NC1 Analog Switch 1—Normally Closed Terminal — 2 — 4 IN Digital Control Input Switch 1, 2, 3, and 4 2 — 4 — IN1, IN2 Digital Control Input Switch 1 and 2 3 3 5 5 NO2 Analog Switch 2—Normally Open Terminal 4 4 6 6 COM2 Analog Switch 2—Common Terminal 5 5 7 7 NC2 Analog Switch 2—Normally Closed Terminal 6 6 8 8 GND Ground 7 7 9 9 NO3 Analog Switch 3—Normally Open Terminal 8 8 10 10 COM3 Analog Switch 3—Common Terminal 9 9 11 11 NC3 Analog Switch 3—Normally Closed Terminal — 10 — 12 VL Logic Power-Supply Input 10 — 12 — IN3, IN4 Digital Control Input Switch 3 and 4 11 11 13 13 NO4 Analog Switch 4—Normally Open Terminal 12 12 14 14 COM4 Analog Switch 4—Common Terminal 13 13 15 15 NC4 Analog Switch 4—Normally Closed Terminal 14 14 16 16 V+ Positive Supply Voltage Input 15 15 1 1 NO1 Analog Switch 1—Normally Open Terminal 16 16 2 2 COM1 Analog Switch 1—Common Terminal — — — — EP Exposed Pad (TQFN Only).
