Exposed Solder Pad Connection
The exposed solder pad on the bottom of the
package must be grounded for proper device
operation.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with 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 rate specified in Table 3.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Switching Frequency
The PE4308 has a maximum 25 kHz switching rate.
Resistor on Pin 1 & 3
A 10 kΩ resistor on the inputs to Pin 1 & 3 (see
Figure 5) will eliminate package resonance between
the RF input pin and the two digital inputs. Specified
attenuation error versus frequency performance is
dependent upon this condition.
