Latch-Up Immunity Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up. 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 specified rating. Switching Frequency Table 3.

Single-pin control mode enables the switch to operate with a single control pin (pin 2) supporting a +3.3 or 5.0-volt CMOS logic input, and requires a dedicated +3.3 or 5.0-volt power supply connection (pin 1). This mode of operation reduces the number of control lines required and simplifies the switch control interface typically derived from a CMOS Processor I/O port. Complementary-pin control mode allows the switch to operate using complementary control pins V1 and V2 (pins 2 & 1), that can be directly driven by +3.3 or 5.0-volt CMOS logic or a suitable Processor I/O port. This enables the PE4251 to operate in positive control voltage mode within the PE4251 operating limits. (c)2008-2019 pSemi Corp. All rights reserved.

Evaluation Board Layouts Evaluation Kit The SPDT switch evaluation kit board was designed to ease customer evaluation of the PE4251 SPDT switch. The RF common port is connected through a 50 transmission line to the bottom SMA connector, J3. Port 1 and Port 2 are connected through 50 transmission lines to two SMA connectors on either side of the board, J4 and J2. A through transmission line connects SMA connectors J5 and J6. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. The board is constructed of a two metal layer FR4 material with a total thickness of 0.0322". The bottom layer provides ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 0.033", trace gaps of 0.010", dielectric thickness of 0.028", copper thickness of 0.0021" and r of 4.3. J1 provides a means for controlling the DC inputs to the device. The second-to-bottom lower right pin (J1-3) is connected to the device V1 input. The second-to-top upper right pin (J1-7) is connected to the device V2 input. Footprints for decoupling capacitors are provided on both V1 and V2 traces. It is the responsibility of the customer to determine proper supply decoupling for their design application. Removing these components from the evaluation board has not been shown to degrade RF performance. PRT-53366 Figure 5. Evaluation Board Schematic NOTES: 1. USE 101-0337-02 PCB.
