Description
The AS179-92LF is a pHEMT GaAs FET single-pole, double-throw
(SPDT) switch. The device features low insertion loss and positive
voltage operation with very low DC power consumption. The
AS179-92LF is manufactured in a compact, low-cost
2.00 x 1.25 mm, 6-pin SC-70 package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
at or below their nominal value.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
