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.
Exposed Solder Pad Connection
The exposed solder pad on the bottom of the
package must be grounded for proper device
operation.
Table 4. DC Electrical Specifications
Note 1:
Both RF ports must be held at 0 V
DC
or DC blocked with an
external series capacitor.
2: Latch Enable (LE) has an internal 100 k
resistor to V
3: Connect pin 12 to GND to enable internal negative voltage
generator. Connect pin 12 to V
SS
(-VDD) to bypass and
disable internal negative voltage generator.
4. Place a 10 k
resistor in series, as close to pin as possible
to avoid frequency resonance.

Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
devices are immune to latch-up.
Switching Frequency
The PE4302 has a maximum 25kHz switching
rate.
Resistor on Pin 1 & 3
A 10 k
resistor on the inputs to Pin 1 & 3 (see
Figure 16) 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.
