1 2.7Ω Low Voltage SPDT Analog Switch in 6-pin SOT363 Features Wide Power Supply Range: 1.8V to 5.5V High andwidth: 300MHz High Off-Isolation: 84d at 1MHz 51d at 10MHz On-Resistance: 2.7Ω(typ) at 5.0V Fast Switching Time t on = 12.0ns; t off = 5.0ns TTL/CMOS Compatible reak-efore-make Switching Rail-to-Rail Signal Range Operation Temperature Range: -40 to 85 Lead (Pb) Free SOT363-6 Package Applications Description The is a Single Wide-andwidth, fast singlepole double-throw (SPDT) CMOS switch featuring an On-Resistance of 2.7 ohm at V CC=5.0V and wide power supply range from 1.8V to 5.5V. It can be used as an analog switch or as a low-delay bus switch. The 300MHz high bandwidth performance supports the high frequency application. reak-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously. lock Diagram A1 1 6 EN Wireless Handsets MP3 Players Portable Electronic Devices Relay Replacement PDAs Audio & Video Signal Routing PCMCIA Cards Computer Peripherals Modems Pin Configuration EN A Function Table EN Function 1 A1 Connected to 0 A2 Connected to Pin Description ASSS A1 A2 SSS: production id Pin Name Type Description PWR Power Supply Ground Ground Input/Output Data Port A1 Input/Output Data Port A2 Input/Output Data Port EN Input Logic Control Signal 1/10
