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
Notes: 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 DD.
3: Connect pin 12 to GND to enable internal negative voltage
generator. Connect pin 12 to V SS (-V DD ) 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. See “Resistor on Pin 1 & 3”
paragraph
?2003-2006 Peregrine Semiconductor Corp. All rights reserved.
The PE4308 has a maximum 25 kHz switching rate.
Resistor on Pin 1 & 3
A 10 k ? 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.
