| STG3699B Low voltage 0.5 max, quad SPDT switch with break-before-make feature Features High speed: - tPD = 1.5 ns (typ.) at VCC = 3.0 V - tPD = 1.5 ns (typ.) at VCC = 2.3 V Ultra low power dissipation: - ICC = 0.2 A (max.) at TA = 85C Low ON resistance VIN = 0 V: - RON = 0.50 (max. TA = 25C) at VCC = 4.3 V - RON = 0.55 (max. TA = 25C) at VCC = 3.0 V - RON = 0.55 (max. TA = 25C) at VCC = 2.7 V Wide operating voltage range: - VCC (OPR) = 1.65 to 4.3 V single supply 4.3 V tolerant and 1.8 V compatible thresholds on digital control input at VCC = 2.3 to 3.0 V Latch-up performance exceed 300 mA (JESD 17) ESD performance (analog chan. vs. GND): HBM > 2 kV (MIL STD 883 method 3015) QFN16L (2.6 x 1.8 mm) Description The STG3699B is a high-speed CMOS low voltage quad analog SPDT (single-pole doublethrow) switch or 2:1 multiplexer/demultiplexer switch fabricated using silicon gate C2MOS technology. Designed to operate from 1.65 to 4.3 V, this device is ideal for portable applications. It offers very low ON resistance (RON < 0.5 ) at VCC = 3.0 V. The nIN inputs are provided to control the independent channel switches nS1 and nS2. The switches nS1 are ON (connected to common ports Dn) when the nIN input is held high and OFF (state of high impedance exists between the two ports) when nIN is held low. The switches nS2 are ON (connected to common ports Dn) when the nIN input is held low and OFF (state of high impedance exists between the two ports) when IN is held high. Additional key features are fast switching speed, break-before-make delay time and ultra low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD and excess transient voltage immunity. The STG3699B is available in the commercial temperature range of -40 to 125C in a QFN16L, 2.6 x 1.8 mm package. Table 1.
