Electrostatic Discharge (ESD) Precautions

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.

series capacitor

3. Connect pin 12 to GND to enable internal negative voltage

internal negative voltage generator

4. Place a 10 kΩ resistor in series, as close to pin as possible to avoid

frequency resonance. See “Resistor on 3” paragraph

Latch-Up Avoidance

devices are immune to latch-up.

Switching Frequency

The PE4307 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.
