Table 3. Absolute Maximum Ratings
Exceeding absolute maximum ratings may cause
permanent damage. Operation should be restricted
to the limits in the Operating Ranges table.
Operation between operating range maximum and
absolute maximum for extended periods may reduce
reliability.

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 PE43404 has a maximum 25 kHz switching rate.
Resistor on Pin 3
A 10 kΩ resistor on the input to Pin 3 (see Figure 5)
will eliminate package resonance between the RF
input pin and the digital input. Specified attenuation
error versus frequency performance is dependent
upon this condition.
