... ASIC design risk. The ISL8499 is offered in small form factor packages, alleviating board space limitations. The ISL8499 consists of four SPDT switches configured as a dual double-pole/double-throw (DPDT) device with two logic control inputs that control two SPDT switches each. The configuration can be used as a dual differential 2-to-1 multiplexer/demultiplexer ...

... ANALYZER GND R L FIGURE 6. CROSSTALK TEST CIRCUIT Detailed Description The ISL8499 is a bidirectional, quad single pole/double throw (SPDT) analog switch that offers precise switching capability from a single 1.65V to 4.5V supply with low on-resistance (0.24Ω) and high speed operation (t = 15ns 13ns). The device is especially well ...

... OPTIONAL PROTECTION DIODE FIGURE 8. OVERVOLTAGE PROTECTION Power-Supply Considerations The ISL8499 construction is typical of most single supply CMOS analog switches, in that they have two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL8499 4 ...
