2 / 8 page  Product Specification PE4271 Page 2 of 8 ©2005 Peregrine Semiconductor Corp. All rights reserved. Document No. 70-0149-03 │ UltraCMOS™ RFIC Solutions Notes: 1. Both RF pins must be held at 0 VDC or require external DC blocking capacitors 2. The exposed pad must be soldered to the ground plane for proper switch performance. Table 2. Pin Descriptions Table 3. Absolute Maximum Ratings 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 rating specified in Table 3. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up. Table 4. DC Electrical Specifications Figure 3. Pin Configuration Table 5. Control Logic Truth Table Exposed Solder Pad (bottom side) V DD GND RF1 RF2 GND CTRL 4 5 6 3 2 1 Device Description The PE4271 high isolation SPST CATV Switch is designed to support CATV applications such as premium channel service connect/disconnect switch blocks. This function is typically performed by bulky and expensive mechanical switches. The high isolation characteristics (60 dB at 1 GHz, 85 dB at 5 MHz), high compression point, and an integrated 75 Ω (0.25 watt) input termination make the PE4271 an ideal, low cost solution. The control logic input pin (CTRL) is typically driven by a 3-volt CMOS logic level signal, and has a threshold of 50% of VDD. For flexibility to support systems that have 5-volt control logic drivers, the control logic input has been designed to handle a 5- volt logic HIGH signal. (A minimal current will be sourced out of the VDD pin when the control logic input voltage level exceeds VDD.) Notes: 1. CTRL accepts both CMOS and TTL voltage leads. Absolute Maximum Ratings are those values listed in the above table. Exceeding these values may cause permanent device damage. Functional operation should be restricted to the limits in the DC Electrical Specifications table. Exposure to absolute maximum ratings for extended periods may affect device reliability.
