Electrostatic Discharge (ESD) Precautions

When handling this CMOS 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

specified rating.

Latch-Up Avoidance

Unlike conventional CMOS devices, SIPAT'S CMOS

devices are immune to latch-up.

Table 4. Operating Ranges

Table 5. 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.

Notes: 1. Pins 3 through 7 may be tied to ground if desired, but

they are not connected to ground internal to the package

2. All RF pins must be DC blocked with an external series

capacitor or held at 0 VDC.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the SP43204 in

the 12-lead 3x3 QFN package is MSL1.

Switching Frequency

The SP43204 has a maximum 25 kHz switching rate.

Switching rate is defined to be the speed at which the

DSA can be toggled across attenuation states.
