| SGM4782 GENERAL DESCRIPTION The SGM4782 is high-speed, low-voltage, low on-resistance, CMOS analog multiplexer/switch that configured as two 4-channel multiplexers. It operates from a single +1.8V to +4.2V power supply. Targeted applications include battery powered equipment that benefit from low RON (0.5) and fast switching speeds (tON = 20 ns, tOFF = 20 ns). The SGM4782 can handle rail-to-rail analog signals and is available in TQFN-16 and TSSOP-16 packages. 0.5, High Speed, Low Voltage Analog Switch / Multiplexer FEATURES - - - - - Voltage Operation: 1. 8 V to 4. 2 V Low On-Resistance: 0.5 (TYP) at 4.2 V Low On-Resistance Flatness -3 dB Bandwidth: 30 MHz Fast Switching Time ( +4.2V ) tON 20 ns tOFF 20 ns Low Crosstalk: -108 dB at 1 MHz Typical Power Consumption (<0.01 W) TTL/CMOS Compatible Rail-to-Rail Input and Output Operation Break-Before-Make Switching Extended Industrial Temperature Range: -40C to +85C Lead (Pb) Free TQFN-16 and TSSOP-16 packages - - - - - - - APPLICATIONS Communication Systems Cell Phones Portable Instrumentation Audio Signal Routing Audio and Video Switching Computer Peripherals Low-Voltage Data-Acquisition Systems PIN CONFIGURATIONSTOP VIEW Function table Control Inputs ENABLE L L L L H = Don't Care.
