Description
The AS211-334 is an FET Single-Pole, Double-Throw (SPDT)
switch for general telecommunications applications. The device
features low insertion loss and positive voltage operation with
very low DC power consumption.
The switch is manufactured in a compact, 1.5 x 1.2 x 0.8 mm,
6-pin Land Grid Array (LGA) 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.

Note: 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. Exceeding any of the limits listed here may result in permanent damage to the device.
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.
Electrical and Mechanical Specifications
The absolute maximum ratings of the AS211-334 are provided in
Table 2. Electrical specifications are provided in Table 3.
Typical performance characteristics of the AS211-334 are
illustrated in Figures 3 through 5.
The state of the AS211-334 is determined by the logic provided in
Table 4.
