It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Optional External VSS Control For proper operation, the VSS_EXT control pin must be grounded or tied to the VSS voltage specified in Table 2 . When the VSS_EXT control pin is grounded, FETs in the switch are biased with an internal negative voltage generator. For applications that require the lowest possible spur performance, VSS_EXT can be applied external y to bypass the internal negative voltage generator. Absolute Maximum Ratings Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be restricted to the limits in Table 2 . Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. ESD Precautions When handling this UltraCMOS device, observe the same precautions as with any other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 1 . Latch-up Immunity Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.

Truth Tables Serial Addressable Register Map Programming Options Parallel/Serial Selection Parallel Mode Interface For direct parallel programming, the LE line should be pulled HIGH. Changing attenuation state control values changes the device state to new attenuation. Direct mode is ideal for manual control of the device (using hardwire, switches, or jumpers).
